'git-diff-{asterisk}' plumbing commands. Can be overridden on the
command line with the `--color[=<when>]` option.
+diff.colorMoved::
+ If set to either a valid `<mode>` or a true value, moved lines
+ in a diff are colored differently, for details of valid modes
+ see '--color-moved' in linkgit:git-diff[1]. If simply set to
+ true the default color mode will be used. When set to false,
+ moved lines are not colored.
+
color.diff.<slot>::
Use customized color for diff colorization. `<slot>` specifies
which part of the patch to use the specified color, and is one
of `context` (context text - `plain` is a historical synonym),
`meta` (metainformation), `frag`
(hunk header), 'func' (function in hunk header), `old` (removed lines),
- `new` (added lines), `commit` (commit headers), or `whitespace`
- (highlighting whitespace errors).
+ `new` (added lines), `commit` (commit headers), `whitespace`
+ (highlighting whitespace errors), `oldMoved` (deleted lines),
+ `newMoved` (added lines), `oldMovedDimmed`, `oldMovedAlternative`,
+ `oldMovedAlternativeDimmed`, `newMovedDimmed`, `newMovedAlternative`
+ and `newMovedAlternativeDimmed` (See the '<mode>'
+ setting of '--color-moved' in linkgit:git-diff[1] for details).
color.decorate.<slot>::
Use customized color for 'git log --decorate' output. `<slot>` is one
sendemail.<identity>.*::

+ found below, taking precedence over those when this
+ identity is selected, through either the command-line or
`sendemail.identity`.
sendemail.aliasesFile::
endif::git-diff[]
It is the same as `--color=never`.
+--color-moved[=<mode>]::
+ Moved lines of code are colored differently.
+ifdef::git-diff[]
+ It can be changed by the `diff.colorMoved` configuration setting.
+endif::git-diff[]
+ The <mode> defaults to 'no' if the option is not given
+ and to 'zebra' if the option with no mode is given.
+ The mode must be one of:
++
+--
+no::
+ Moved lines are not highlighted.
+default::
+ Is a synonym for `zebra`. This may change to a more sensible mode
+ in the future.
+plain::
+ Any line that is added in one location and was removed
+ in another location will be colored with 'color.diff.newMoved'.
+ Similarly 'color.diff.oldMoved' will be used for removed lines
+ that are added somewhere else in the diff. This mode picks up any
+ moved line, but it is not very useful in a review to determine
+ if a block of code was moved without permutation.
+zebra::
+ Blocks of moved text of at least 20 alphanumeric characters
+ are detected greedily. The detected blocks are
+ painted using either the 'color.diff.{old,new}Moved' color or
+ 'color.diff.{old,new}MovedAlternative'. The change between
+ the two colors indicates that a new block was detected.
+dimmed_zebra::
+ Similar to 'zebra', but additional dimming of uninteresting parts
+ of moved code is performed. The bordering lines of two adjacent
+ blocks are considered interesting, the rest is uninteresting.

+
--word-diff[=<mode>]::
Show a word diff, using the <mode> to delimit changed words.
By default, words are delimited by whitespace; see
branch.autoSetupMerge configuration variable is true.
--set-upstream::
- If specified branch does not exist yet or if `--force` has been
- given, acts exactly like `--track`. Otherwise sets up configuration
- like `--track` would when creating the branch, except that where
- branch points to is not changed.
+ As this option had confusing syntax, it is no longer supported.
+ Please use `--track` or `--set-upstream-to` instead.

SYNOPSIS
--------
[verse]
-'git interpret-trailers' [--in-place] [--trim-empty] [(--trailer <token>[(=|:)<value>])...] [<file>...]
+'git interpret-trailers' [options] [(--trailer <token>[(=|:)<value>])...] [<file>...]
+'git interpret-trailers' [options] [--parse] [<file>...]
DESCRIPTION
-----------
-Help adding 'trailers' lines, that look similar to RFC 822 e-mail
+Help parsing or adding 'trailers' lines, that look similar to RFC 822 e-mail
headers, at the end of the otherwise free-form part of a commit
message.
This command reads some patches or commit messages from either the
-<file> arguments or the standard input if no <file> is specified. Then
-this command applies the arguments passed using the `--trailer`
-option, if any, to the commit message part of each input file. The
-result is emitted on the standard output.
+<file> arguments or the standard input if no <file> is specified. If
+`--parse` is specified, the output consists of the parsed trailers.
+
+Otherwise, this command applies the arguments passed using the
+`--trailer` option, if any, to the commit message part of each input
+file. The result is emitted on the standard output.
Some configuration variables control the way the `--trailer` arguments
are applied to each commit message and the way any existing trailer in
trailer to the input messages. See the description of this
command.
+--where <placement>::
+--no-where::
+ Specify where all new trailers will be added. A setting
+ provided with '--where' overrides all configuration variables
+ and applies to all '--trailer' options until the next occurrence of
+ '--where' or '--no-where'.
+
+--if-exists <action>::
+--no-if-exists::
+ Specify what action will be performed when there is already at
+ least one trailer with the same <token> in the message. A setting
+ provided with '--if-exists' overrides all configuration variables
+ and applies to all '--trailer' options until the next occurrence of
+ '--if-exists' or '--no-if-exists'.
+
+--if-missing <action>::
+--no-if-missing::
+ Specify what action will be performed when there is no other
+ trailer with the same <token> in the message. A setting
+ provided with '--if-missing' overrides all configuration variables
+ and applies to all '--trailer' options until the next occurrence of
+ '--if-missing' or '--no-if-missing'.
+
+--only-trailers::
+ Output only the trailers, not any other parts of the input.
+
+--only-input::
+ Output only trailers that exist in the input; do not add any
+ from the command-line or by following configured `trailer.*`
+ rules.
+
+--unfold::
+ Remove any whitespace-continuation in trailers, so that each
+ trailer appears on a line by itself with its full content.
+
+--parse::
+ A convenience alias for `--only-trailers --only-input
+ --unfold`.
+
CONFIGURATION VARIABLES
-----------------------
configuration variable and it overrides what is specified by
that option for trailers with the specified <token>.
-trailer.<token>.ifexist::
- This option takes the same values as the 'trailer.ifexist'
+trailer.<token>.ifexists::
+ This option takes the same values as the 'trailer.ifexists'
configuration variable and it overrides what is specified by
that option for trailers with the specified <token>.
-------
include::merge-options.txt[]
+--signoff::
+ Add Signed-off-by line by the committer at the end of the commit
+ log message. The meaning of a signoff depends on the project,
+ but it typically certifies that committer has
+ the rights to submit this work under the same license and
+ agrees to a Developer Certificate of Origin
+ (see http://developercertificate.org/ for more information).
+
-S[<keyid>]::
--gpg-sign[=<keyid>]::
GPG-sign the resulting merge commit. The `keyid` argument is
- '%><(<N>)', '%><|(<N>)': similar to '% <(<N>)', '%<|(<N>)'
respectively, but padding both sides (i.e. the text is centered)
- %(trailers): display the trailers of the body as interpreted by
- linkgit:git-interpret-trailers[1]
+ linkgit:git-interpret-trailers[1]. If the `:only` option is given,
+ omit non-trailer lines from the trailer block. If the `:unfold`
+ option is given, behave as if interpret-trailer's `--unfold` option
+ was given. E.g., `%(trailers:only:unfold)` to do both.
NOTE: Some placeholders may depend on other options given to the
revision traversal engine. For example, the `%g*` reflog options will

- Initialize a `tree_desc` and decode its first entry given the sha1 of

- identifier and NULL otherwise.
