DESCRIPTION
       List commits that are reachable by following the parent links from the given commit(s), but exclude commits
       that are reachable from the one(s) given with a ^ in front of them. The output is given in reverse
       means "list all the commits which are reachable from foo or bar, but not from baz".

       A special notation "<commit1>..<commit2>" can be used as a short-hand for "^'<commit1>' <commit2>". For
       example, either of the following may be used interchangeably:

                   $ git rev-list origin..HEAD
                   $ git rev-list HEAD ^origin


       Another special notation is "<commit1>...<commit2>" which is useful for merges. The resulting set of commits
       is the symmetric difference between the two operands. The following two commands are equivalent:

                   $ git rev-list A B --not $(git merge-base --all A B)
                   $ git rev-list A...B


       rev-list is a very essential Git command, since it provides the ability to build and traverse commit ancestry
       graphs. For this reason, it has a lot of different options that enables it to be used by commands as different
       as git bisect and git repack.

OPTIONS
   Commit Limiting
       Besides specifying a range of commits that should be listed using the special notations explained in the
       description, additional commit limiting may be applied.

       Using more options generally further limits the output (e.g. --since=<date1> limits to commits newer than
       <date1>, and using it with --grep=<pattern> further limits to commits whose log message has a line that
       matches <pattern>), unless otherwise noted.

       Note that these are applied before commit ordering and formatting options, such as --reverse.

       -<number>, -n <number>, --max-count=<number>
           Limit the number of commits to output.

       --skip=<number>
           Skip number commits before starting to show the commit output.

       --since=<date>, --after=<date>
           Show commits more recent than a specific date.

       --until=<date>, --before=<date>
           Show commits older than a specific date.

       --max-age=<timestamp>, --min-age=<timestamp>
           Limit the commits output to specified time range.

       --author=<pattern>, --committer=<pattern>
           Limit the commits output to ones with author/committer header lines that match the specified pattern
           (regular expression). With more than one --author=<pattern>, commits whose author matches any of the given
           patterns are chosen (similarly for multiple --committer=<pattern>).

       --grep-reflog=<pattern>
           Limit the commits output to ones with reflog entries that match the specified pattern (regular
           expression). With more than one --grep-reflog, commits whose reflog message matches any of the given

       -i, --regexp-ignore-case
           Match the regexp limiting patterns without regard to letters case.

       --basic-regexp
           Consider the limiting patterns to be basic regular expressions; this is the default.

       -E, --extended-regexp
           Consider the limiting patterns to be extended regular expressions instead of the default basic regular
           expressions.

       -F, --fixed-strings
           Consider the limiting patterns to be fixed strings (don’t interpret pattern as a regular expression).

       --perl-regexp
           Consider the limiting patterns to be Perl-compatible regexp. Requires libpcre to be compiled in.

       --remove-empty
           Stop when a given path disappears from the tree.

       --merges
           Print only merge commits. This is exactly the same as --min-parents=2.

       --no-merges
           Do not print commits with more than one parent. This is exactly the same as --max-parents=1.

       --min-parents=<number>, --max-parents=<number>, --no-min-parents, --no-max-parents
           Show only commits which have at least (or at most) that many commits. In particular, --max-parents=1 is
           the same as --no-merges, --min-parents=2 is the same as --merges.  --max-parents=0 gives all root commits
           and --min-parents=3 all octopus merges.

           --no-min-parents and --no-max-parents reset these limits (to no limit) again. Equivalent forms are
           --min-parents=0 (any commit has 0 or more parents) and --max-parents=-1 (negative numbers denote no upper
           limit).

       --first-parent
           Follow only the first parent commit upon seeing a merge commit. This option can give a better overview
           when viewing the evolution of a particular topic branch, because merges into a topic branch tend to be
           only about adjusting to updated upstream from time to time, and this option allows you to ignore the
           individual commits brought in to your history by such a merge.

       --not
           Reverses the meaning of the ^ prefix (or lack thereof) for all following revision specifiers, up to the
           next --not.

       --all
           Pretend as if all the refs in refs/ are listed on the command line as <commit>.

       --branches[=<pattern>]
           Pretend as if all the refs in refs/heads are listed on the command line as <commit>. If <pattern> is
           given, limit branches to ones matching given shell glob. If pattern lacks ?, *, or [, /* at the end is
           implied.

       --tags[=<pattern>]
           Pretend as if all the refs in refs/tags are listed on the command line as <commit>. If <pattern> is given,

       --ignore-missing
           Upon seeing an invalid object name in the input, pretend as if the bad input was not given.

       --stdin
           In addition to the <commit> listed on the command line, read them from the standard input. If a --
           separator is seen, stop reading commits and start reading paths to limit the result.

       --quiet
           Don’t print anything to standard output. This form is primarily meant to allow the caller to test the exit
           status to see if a range of objects is fully connected (or not). It is faster than redirecting stdout to
           /dev/null as the output does not have to be formatted.

       --cherry-mark
           Like --cherry-pick (see below) but mark equivalent commits with = rather than omitting them, and
           inequivalent ones with +.

       --cherry-pick
           Omit any commit that introduces the same change as another commit on the "other side" when the set of
           commits are limited with symmetric difference.

           For example, if you have two branches, A and B, a usual way to list all commits on only one side of them
           is with --left-right (see the example below in the description of the --left-right option). It however
           shows the commits that were cherry-picked from the other branch (for example, "3rd on b" may be
           cherry-picked from branch A). With this option, such pairs of commits are excluded from the output.

       --left-only, --right-only
           List only commits on the respective side of a symmetric range, i.e. only those which would be marked <
           resp.  > by --left-right.

           For example, --cherry-pick --right-only A...B omits those commits from B which are in A or are
           patch-equivalent to a commit in A. In other words, this lists the + commits from git cherry A B. More
           precisely, --cherry-pick --right-only --no-merges gives the exact list.

       --cherry
           A synonym for --right-only --cherry-mark --no-merges; useful to limit the output to the commits on our
           side and mark those that have been applied to the other side of a forked history with git log --cherry
           upstream...mybranch, similar to git cherry upstream mybranch.

       -g, --walk-reflogs
           Instead of walking the commit ancestry chain, walk reflog entries from the most recent one to older ones.
           When this option is used you cannot specify commits to exclude (that is, ^commit, commit1..commit2, nor
           commit1...commit2 notations cannot be used).

           With --pretty format other than oneline (for obvious reasons), this causes the output to have two extra
           lines of information taken from the reflog. By default, commit@{Nth} notation is used in the output. When
           the starting commit is specified as commit@{now}, output also uses commit@{timestamp} notation instead.
           Under --pretty=oneline, the commit message is prefixed with this information on the same line. This option
           cannot be combined with --reverse. See also git-reflog(1).

       --merge
           After a failed merge, show refs that touch files having a conflict and don’t exist on all heads to merge.

       --boundary
           Output uninteresting commits at the boundary, which are usually not shown.
           Commits that are referred by some branch or tag are selected.

       Note that extra commits can be shown to give a meaningful history.

       The following options affect the way the simplification is performed:

       Default mode
           Simplifies the history to the simplest history explaining the final state of the tree. Simplest because it
           prunes some side branches if the end result is the same (i.e. merging branches with the same content)

       --full-history
           Same as the default mode, but does not prune some history.

       --dense
           Only the selected commits are shown, plus some to have a meaningful history.

       --sparse
           All commits in the simplified history are shown.

       --simplify-merges
           Additional option to --full-history to remove some needless merges from the resulting history, as there
           are no selected commits contributing to this merge.

       --ancestry-path
           When given a range of commits to display (e.g.  commit1..commit2 or commit2 ^commit1), only display
           commits that exist directly on the ancestry chain between the commit1 and commit2, i.e. commits that are
           both descendants of commit1, and ancestors of commit2.

       A more detailed explanation follows.

       Suppose you specified foo as the <paths>. We shall call commits that modify foo !TREESAME, and the rest
       TREESAME. (In a diff filtered for foo, they look different and equal, respectively.)

       In the following, we will always refer to the same example history to illustrate the differences between
       simplification settings. We assume that you are filtering for a file foo in this commit graph:

                     .-A---M---N---O---P
                    /     /   /   /   /
                   I     B   C   D   E
                    \   /   /   /   /
                     `-------------'


       The horizontal line of history A---P is taken to be the first parent of each merge. The commits are:

       ·   I is the initial commit, in which foo exists with contents "asdf", and a file quux exists with contents
           "quux". Initial commits are compared to an empty tree, so I is !TREESAME.

       ·   In A, foo contains just "foo".

       ·   B contains the same change as A. Its merge M is trivial and hence TREESAME to all parents.

       ·   C does not change foo, but its merge N changes it to "foobar", so it is not TREESAME to any parent.


           there are several TREESAME parents, follow only one of them.) Otherwise, follow all parents.

           This results in:

                         .-A---N---O
                        /     /   /
                       I---------D

           Note how the rule to only follow the TREESAME parent, if one is available, removed B from consideration
           entirely.  C was considered via N, but is TREESAME. Root commits are compared to an empty tree, so I is
           !TREESAME.

           Parent/child relations are only visible with --parents, but that does not affect the commits selected in
           default mode, so we have shown the parent lines.

       --full-history without parent rewriting
           This mode differs from the default in one point: always follow all parents of a merge, even if it is
           TREESAME to one of them. Even if more than one side of the merge has commits that are included, this does
           not imply that the merge itself is! In the example, we get

                       I  A  B  N  D  O

           P and M were excluded because they are TREESAME to a parent.  E, C and B were all walked, but only B was
           !TREESAME, so the others do not appear.

           Note that without parent rewriting, it is not really possible to talk about the parent/child relationships
           between the commits, so we show them disconnected.

       --full-history with parent rewriting
           Ordinary commits are only included if they are !TREESAME (though this can be changed, see --sparse below).

           Merges are always included. However, their parent list is rewritten: Along each parent, prune away commits
           that are not included themselves. This results in

                         .-A---M---N---O---P
                        /     /   /   /   /
                       I     B   /   D   /
                        \   /   /   /   /
                         `-------------'

           Compare to --full-history without rewriting above. Note that E was pruned away because it is TREESAME, but
           the parent list of P was rewritten to contain E's parent I. The same happened for C and N. Note also that
           P was included despite being TREESAME.

       In addition to the above settings, you can change whether TREESAME affects inclusion:

       --dense
           Commits that are walked are included if they are not TREESAME to any parent.

       --sparse
           All commits that are walked are included.

           Note that without --full-history, this still simplifies merges: if one of the parents is TREESAME, we
           follow only that one, so the other sides of the merge are never walked.

               commit, or !TREESAME, it remains. Otherwise, it is replaced with its only parent.

           The effect of this is best shown by way of comparing to --full-history with parent rewriting. The example
           turns into:

                         .-A---M---N---O
                        /     /       /
                       I     B       D
                        \   /       /
                         `---------'

           Note the major differences in N and P over --full-history:

           ·   N's parent list had I removed, because it is an ancestor of the other parent M. Still, N remained
               because it is !TREESAME.

           ·   P's parent list similarly had I removed.  P was then removed completely, because it had one parent and
               is TREESAME.

       Finally, there is a fifth simplification mode available:

       --ancestry-path
           Limit the displayed commits to those directly on the ancestry chain between the "from" and "to" commits in
           the given commit range. I.e. only display commits that are ancestor of the "to" commit, and descendants of
           the "from" commit.

           As an example use case, consider the following commit history:

                           D---E-------F
                          /     \       \
                         B---C---G---H---I---J
                        /                     \
                       A-------K---------------L--M

           A regular D..M computes the set of commits that are ancestors of M, but excludes the ones that are
           ancestors of D. This is useful to see what happened to the history leading to M since D, in the sense that
           "what does M have that did not exist in D". The result in this example would be all the commits, except A
           and B (and D itself, of course).

           When we want to find out what commits in M are contaminated with the bug introduced by D and need fixing,
           however, we might want to view only the subset of D..M that are actually descendants of D, i.e. excluding
           C and K. This is exactly what the --ancestry-path option does. Applied to the D..M range, it results in:

                               E-------F
                                \       \
                                 G---H---I---J
                                              \
                                               L--M


       The --simplify-by-decoration option allows you to view only the big picture of the topology of the history, by
       omitting commits that are not referenced by tags. Commits are marked as !TREESAME (in other words, kept after
       history simplification rules described above) if (1) they are referenced by tags, or (2) they change the
       contents of the paths given on the command line. All other commits are marked as TREESAME (subject to be
       outputs midpoint, the output of the two commands

                   $ git rev-list foo ^midpoint
                   $ git rev-list midpoint ^bar ^baz


       would be of roughly the same length. Finding the change which introduces a regression is thus reduced to a
       binary search: repeatedly generate and test new 'midpoint’s until the commit chain is of length one.

       --bisect-vars
           This calculates the same as --bisect, except that refs in refs/bisect/ are not used, and except that this
           outputs text ready to be eval’ed by the shell. These lines will assign the name of the midpoint revision
           to the variable bisect_rev, and the expected number of commits to be tested after bisect_rev is tested to
           bisect_nr, the expected number of commits to be tested if bisect_rev turns out to be good to bisect_good,
           the expected number of commits to be tested if bisect_rev turns out to be bad to bisect_bad, and the
           number of commits we are bisecting right now to bisect_all.

       --bisect-all
           This outputs all the commit objects between the included and excluded commits, ordered by their distance
           to the included and excluded commits. Refs in refs/bisect/ are not used. The farthest from them is
           displayed first. (This is the only one displayed by --bisect.)

           This is useful because it makes it easy to choose a good commit to test when you want to avoid to test
           some of them for some reason (they may not compile for example).

           This option can be used along with --bisect-vars, in this case, after all the sorted commit objects, there
           will be the same text as if --bisect-vars had been used alone.

   Commit Ordering
       By default, the commits are shown in reverse chronological order.

       --date-order
           Show no parents before all of its children are shown, but otherwise show commits in the commit timestamp
           order.

       --topo-order
           Show no parents before all of its children are shown, and avoid showing commits on multiple lines of
           history intermixed.

           For example, in a commit history like this:

                   ---1----2----4----7
                       \              \
                        3----5----6----8---

           where the numbers denote the order of commit timestamps, git rev-list and friends with --date-order show
           the commits in the timestamp order: 8 7 6 5 4 3 2 1.

           With --topo-order, they would show 8 6 5 3 7 4 2 1 (or 8 7 4 2 6 5 3 1); some older commits are shown
           before newer ones in order to avoid showing the commits from two parallel development track mixed
           together.

       --reverse
           Output the commits in reverse order. Cannot be combined with --walk-reflogs.

       --unpacked
           Only useful with --objects; print the object IDs that are not in packs.

       --no-walk[=(sorted|unsorted)]
           Only show the given commits, but do not traverse their ancestors. This has no effect if a range is
           specified. If the argument "unsorted" is given, the commits are show in the order they were given on the
           command line. Otherwise (if "sorted" or no argument was given), the commits are show in reverse
           chronological order by commit time.

       --do-walk
           Overrides a previous --no-walk.

   Commit Formatting
       Using these options, git-rev-list(1) will act similar to the more specialized family of commit log tools: git-
       log(1), git-show(1), and git-whatchanged(1)

       --pretty[=<format>], --format=<format>
           Pretty-print the contents of the commit logs in a given format, where <format> can be one of oneline,
           short, medium, full, fuller, email, raw and format:<string>. See the "PRETTY FORMATS" section for some
           additional details for each format. When omitted, the format defaults to medium.

           Note: you can specify the default pretty format in the repository configuration (see git-config(1)).

       --abbrev-commit
           Instead of showing the full 40-byte hexadecimal commit object name, show only a partial prefix. Non
           default number of digits can be specified with "--abbrev=<n>" (which also modifies diff output, if it is
           displayed).

           This should make "--pretty=oneline" a whole lot more readable for people using 80-column terminals.

       --no-abbrev-commit
           Show the full 40-byte hexadecimal commit object name. This negates --abbrev-commit and those options which
           imply it such as "--oneline". It also overrides the log.abbrevCommit variable.

       --oneline
           This is a shorthand for "--pretty=oneline --abbrev-commit" used together.

       --encoding[=<encoding>]
           The commit objects record the encoding used for the log message in their encoding header; this option can
           be used to tell the command to re-code the commit log message in the encoding preferred by the user. For
           non plumbing commands this defaults to UTF-8.

       --notes[=<ref>]
           Show the notes (see git-notes(1)) that annotate the commit, when showing the commit log message. This is
           the default for git log, git show and git whatchanged commands when there is no --pretty, --format nor
           --oneline option given on the command line.

           By default, the notes shown are from the notes refs listed in the core.notesRef and notes.displayRef
           variables (or corresponding environment overrides). See git-config(1) for more details.

           With an optional <ref> argument, show this notes ref instead of the default notes ref(s). The ref is taken
           to be in refs/notes/ if it is not qualified.


       --show-signature
           Check the validity of a signed commit object by passing the signature to gpg --verify and show the output.

       --relative-date
           Synonym for --date=relative.

       --date=(relative|local|default|iso|rfc|short|raw)
           Only takes effect for dates shown in human-readable format, such as when using "--pretty".  log.date
           config variable sets a default value for log command’s --date option.

           --date=relative shows dates relative to the current time, e.g. "2 hours ago".

           --date=local shows timestamps in user’s local timezone.

           --date=iso (or --date=iso8601) shows timestamps in ISO 8601 format.

           --date=rfc (or --date=rfc2822) shows timestamps in RFC 2822 format, often found in E-mail messages.

           --date=short shows only date but not time, in YYYY-MM-DD format.

           --date=raw shows the date in the internal raw Git format %s %z format.

           --date=default shows timestamps in the original timezone (either committer’s or author’s).

       --header
           Print the contents of the commit in raw-format; each record is separated with a NUL character.

       --parents
           Print also the parents of the commit (in the form "commit parent..."). Also enables parent rewriting, see
           History Simplification below.

       --children
           Print also the children of the commit (in the form "commit child..."). Also enables parent rewriting, see
           History Simplification below.

       --timestamp
           Print the raw commit timestamp.

       --left-right
           Mark which side of a symmetric diff a commit is reachable from. Commits from the left side are prefixed
           with < and those from the right with >. If combined with --boundary, those commits are prefixed with -.

           For example, if you have this topology:

                            y---b---b  branch B
                           / \ /
                          /   .
                         /   / \
                        o---x---a---a  branch A

           you would get an output like this:

                       $ git rev-list --left-right --boundary --pretty=oneline A...B


           This enables parent rewriting, see History Simplification below.

           This implies the --topo-order option by default, but the --date-order option may also be specified.

       --count
           Print a number stating how many commits would have been listed, and suppress all other output. When used
           together with --left-right, instead print the counts for left and right commits, separated by a tab. When
           used together with --cherry-mark, omit patch equivalent commits from these counts and print the count for
           equivalent commits separated by a tab.

PRETTY FORMATS
       If the commit is a merge, and if the pretty-format is not oneline, email or raw, an additional line is
       inserted before the Author: line. This line begins with "Merge: " and the sha1s of ancestral commits are
       printed, separated by spaces. Note that the listed commits may not necessarily be the list of the direct
       parent commits if you have limited your view of history: for example, if you are only interested in changes
       related to a certain directory or file.

       There are several built-in formats, and you can define additional formats by setting a pretty.<name> config
       option to either another format name, or a format: string, as described below (see git-config(1)). Here are
       the details of the built-in formats:

       ·   oneline

               <sha1> <title line>

           This is designed to be as compact as possible.

       ·   short

               commit <sha1>
               Author: <author>

               <title line>

       ·   medium

               commit <sha1>
               Author: <author>
               Date:   <author date>

               <title line>

               <full commit message>

       ·   full

               commit <sha1>
               Author: <author>
               Commit: <committer>

               <title line>

               <full commit message>

       ·   email

               From <sha1> <date>
               From: <author>
               Date: <author date>
               Subject: [PATCH] <title line>

               <full commit message>

       ·   raw

           The raw format shows the entire commit exactly as stored in the commit object. Notably, the SHA-1s are
           displayed in full, regardless of whether --abbrev or --no-abbrev are used, and parents information show
           the true parent commits, without taking grafts nor history simplification into account.

       ·   format:<string>

           The format:<string> format allows you to specify which information you want to show. It works a little bit
           like printf format, with the notable exception that you get a newline with %n instead of \n.

           E.g, format:"The author of %h was %an, %ar%nThe title was >>%s<<%n" would show something like this:

               The author of fe6e0ee was Junio C Hamano, 23 hours ago
               The title was >>t4119: test autocomputing -p<n> for traditional diff input.<<

           The placeholders are:

           ·   %H: commit hash

           ·   %h: abbreviated commit hash

           ·   %T: tree hash

           ·   %t: abbreviated tree hash

           ·   %P: parent hashes

           ·   %p: abbreviated parent hashes

           ·   %an: author name

           ·   %aN: author name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %ae: author email

           ·   %aE: author email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %ad: author date (format respects --date= option)

           ·   %aD: author date, RFC2822 style

           ·   %ar: author date, relative

           ·   %cd: committer date

           ·   %cD: committer date, RFC2822 style

           ·   %cr: committer date, relative

           ·   %ct: committer date, UNIX timestamp

           ·   %ci: committer date, ISO 8601 format

           ·   %d: ref names, like the --decorate option of git-log(1)

           ·   %e: encoding

           ·   %s: subject

           ·   %f: sanitized subject line, suitable for a filename

           ·   %b: body

           ·   %B: raw body (unwrapped subject and body)

           ·   %N: commit notes

           ·   %GG: raw verification message from GPG for a signed commit

           ·   %G?: show "G" for a Good signature, "B" for a Bad signature, "U" for a good, untrusted signature and
               "N" for no signature

           ·   %GS: show the name of the signer for a signed commit

           ·   %GK: show the key used to sign a signed commit

           ·   %gD: reflog selector, e.g., refs/stash@{1}

           ·   %gd: shortened reflog selector, e.g., stash@{1}

           ·   %gn: reflog identity name

           ·   %gN: reflog identity name (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %ge: reflog identity email

           ·   %gE: reflog identity email (respecting .mailmap, see git-shortlog(1) or git-blame(1))

           ·   %gs: reflog subject

           ·   %Cred: switch color to red

           ·   %Cgreen: switch color to green

           ·   %Cblue: switch color to blue

           ·   %Creset: reset color

           ·   %x00: print a byte from a hex code

           ·   %w([<w>[,<i1>[,<i2>]]]): switch line wrapping, like the -w option of git-shortlog(1).

           ·   %<(<N>[,trunc|ltrunc|mtrunc]): make the next placeholder take at least N columns, padding spaces on
               the right if necessary. Optionally truncate at the beginning (ltrunc), the middle (mtrunc) or the end
               (trunc) if the output is longer than N columns. Note that truncating only works correctly with N >= 2.

           ·   %<|(<N>): make the next placeholder take at least until Nth columns, padding spaces on the right if
               necessary

           ·   %>(<N>), %>|(<N>): similar to %<(<N>), %<|(<N>) respectively, but padding spaces on the left

           ·   %>>(<N>), %>>|(<N>): similar to %>(<N>), %>|(<N>) respectively, except that if the next placeholder
               takes more spaces than given and there are spaces on its left, use those spaces

           ·   %><(<N>), %><|(<N>): similar to % <(<N>), %<|(<N>) respectively, but padding both sides (i.e. the text
               is centered)

           Note
           Some placeholders may depend on other options given to the revision traversal engine. For example, the %g*
           reflog options will insert an empty string unless we are traversing reflog entries (e.g., by git log -g).
           The %d placeholder will use the "short" decoration format if --decorate was not already provided on the
           command line.

       If you add a + (plus sign) after % of a placeholder, a line-feed is inserted immediately before the expansion
       if and only if the placeholder expands to a non-empty string.

       If you add a - (minus sign) after % of a placeholder, line-feeds that immediately precede the expansion are
       deleted if and only if the placeholder expands to an empty string.

       If you add a ` ` (space) after % of a placeholder, a space is inserted immediately before the expansion if and
       only if the placeholder expands to a non-empty string.

       ·   tformat:

           The tformat: format works exactly like format:, except that it provides "terminator" semantics instead of
           "separator" semantics. In other words, each commit has the message terminator character (usually a
           newline) appended, rather than a separator placed between entries. This means that the final entry of a
           single-line format will be properly terminated with a new line, just as the "oneline" format does. For
           example:

               $ git log -2 --pretty=format:%h 4da45bef \
                 | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
               4da45be
               7134973 -- NO NEWLINE

               $ git log -2 --pretty=tformat:%h 4da45bef \
                 | perl -pe '$_ .= " -- NO NEWLINE\n" unless /\n/'
               4da45be
               7134973

           In addition, any unrecognized string that has a % in it is interpreted as if it has tformat: in front of
