+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
+linkgit: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>
+
+* 'fuller'
+
+ commit <sha1>
+ Author: <author>
+ AuthorDate: <author date>
+ Commit: <committer>
+ CommitDate: <committer date>
+
+ <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 or history
+simplification into account. Note that this format affects the way
+commits are displayed, but not the way the diff is shown e.g. with
+`git log --raw`. To get full object names in a raw diff format,
+use `--no-abbrev`.
+
+* '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 linkgit:git-shortlog[1]
+ or linkgit:git-blame[1])
+- '%ae': author email
+- '%aE': author email (respecting .mailmap, see
+ linkgit:git-shortlog[1] or linkgit:git-blame[1])
+- '%ad': author date (format respects --date= option)
+- '%aD': author date, RFC2822 style
+- '%ar': author date, relative
+- '%at': author date, UNIX timestamp
+- '%ai': author date, ISO 8601-like format
+- '%aI': author date, strict ISO 8601 format
+- '%cn': committer name
+- '%cN': committer name (respecting .mailmap, see
+ linkgit:git-shortlog[1] or linkgit:git-blame[1])
+- '%ce': committer email
+- '%cE': committer email (respecting .mailmap, see
+ linkgit:git-shortlog[1] or linkgit:git-blame[1])
+- '%cd': committer date (format respects --date= option)
+- '%cD': committer date, RFC2822 style
+- '%cr': committer date, relative
+- '%ct': committer date, UNIX timestamp
+- '%ci': committer date, ISO 8601-like format
+- '%cI': committer date, strict ISO 8601 format
+- '%d': ref names, like the --decorate option of linkgit:git-log[1]
+- '%D': ref names without the " (", ")" wrapping.
+- '%e': encoding
+- '%s': subject
+- '%f': sanitized subject line, suitable for a filename
+- '%b': body
+- '%B': raw body (unwrapped subject and body)
+ifndef::git-rev-list[]
+- '%N': commit notes
+endif::git-rev-list[]
+- '%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
+ linkgit:git-shortlog[1] or linkgit:git-blame[1])
+- '%ge': reflog identity email
+- '%gE': reflog identity email (respecting .mailmap, see
+ linkgit:git-shortlog[1] or linkgit:git-blame[1])
+- '%gs': reflog subject
+- '%Cred': switch color to red
+- '%Cgreen': switch color to green
+- '%Cblue': switch color to blue
+- '%Creset': reset color
+- '%C(...)': color specification, as described in color.branch.* config option;
+ adding `auto,` at the beginning will emit color only when colors are
+ enabled for log output (by `color.diff`, `color.ui`, or `--color`, and
+ respecting the `auto` settings of the former if we are going to a
+ terminal). `auto` alone (i.e. `%C(auto)`) will turn on auto coloring
+ on the next placeholders until the color is switched again.
+- '%m': left, right or boundary mark
+- '%n': newline
+- '%%': a raw '%'
+- '%x00': print a byte from a hex code
+- '%w([<w>[,<i1>[,<i2>]]])': switch line wrapping, like the -w option of
+ linkgit: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` and `%D` placeholders 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 '$_ .= " -- NO NEWLINE\n" unless /\n/'
+4da45be
+7134973
+---------------------
++
+In addition, any unrecognized string that has a `%` in it is interpreted
+as if it has `tformat:` in front of it. For example, these two are
+equivalent:
++
+---------------------
+$ git log -2 --pretty=tformat:%h 4da45bef
+$ git log -2 --pretty=%h 4da45bef
+---------------------
