Spend extra time to make sure the smallest possible

-Without this option, each pathname output will have TAB, LF, double quotes,
-and backslash characters replaced with `\t`, `\n`, `\"`, and `\\`,
-respectively, and the pathname will be enclosed in double quotes if
-any of those replacements occurred.
+Without this option, pathnames with "unusual" characters are quoted as

--name-only::
Show only names of changed files.
of the `--diff-filter` option on what the status letters mean.
--submodule[=<format>]::
- Specify how differences in submodules are shown. When `--submodule`
- or `--submodule=log` is given, the 'log' format is used. This format lists
- the commits in the range like linkgit:git-submodule[1] `summary` does.
- Omitting the `--submodule` option or specifying `--submodule=short`,
- uses the 'short' format. This format just shows the names of the commits
- at the beginning and end of the range. Can be tweaked via the
- `diff.submodule` configuration variable.

+ is specified, the 'diff' format is used. This format shows an
+ inline diff of the changes in the submodule contents between the
+ commit range. Defaults to `diff.submodule` or the 'short' format
+ if the config option is unset.
--color[=<when>]::
Show colored diff.
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
with --exit-code.
--ws-error-highlight=<kind>::
- Highlight whitespace errors on lines specified by <kind>
- in the color specified by `color.diff.whitespace`. <kind>
- is a comma separated list of `old`, `new`, `context`. When
- this option is not given, only whitespace errors in `new`
- lines are highlighted. E.g. `--ws-error-highlight=new,old`
- highlights whitespace errors on both deleted and added lines.
- `all` can be used as a short-hand for `old,new,context`.
+ Highlight whitespace errors in the `context`, `old` or `new`
+ lines of the diff. Multiple values are separated by comma,
+ `none` resets previous values, `default` reset the list to
+ `new` and `all` is a shorthand for `old,new,context`. When
+ this option is not given, and the configuration variable
+ `diff.wsErrorHighlight` is not set, only whitespace errors in
+ `new` lines are highlighted. The whitespace errors are colored
+ whith `color.diff.whitespace`.
endif::git-format-patch[]
the diff between the preimage and `/dev/null`. The resulting patch
is not meant to be applied with `patch` or `git apply`; this is
solely for people who want to just concentrate on reviewing the
- text after the change. In addition, the output obviously lack
+ text after the change. In addition, the output obviously lacks
enough information to apply such a patch in reverse, even manually,
hence the name of the option.
+
endif::git-format-patch[]
-O<orderfile>::
- Output the patch in the order specified in the
- <orderfile>, which has one shell glob pattern per line.
+ Control the order in which files appear in the output.
This overrides the `diff.orderFile` configuration variable
(see linkgit:git-config[1]). To cancel `diff.orderFile`,
use `-O/dev/null`.
++
+The output order is determined by the order of glob patterns in
+<orderfile>.
+All files with pathnames that match the first pattern are output
+first, all files with pathnames that match the second pattern (but not
+the first) are output next, and so on.
+All files with pathnames that do not match any pattern are output
+last, as if there was an implicit match-all pattern at the end of the
+file.
+If multiple pathnames have the same rank (they match the same pattern
+but no earlier patterns), their output order relative to each other is
+the normal order.
++
+<orderfile> is parsed as follows:
++
+--
+ - Blank lines are ignored, so they can be used as separators for
+ readability.
+
+ - Lines starting with a hash ("`#`") are ignored, so they can be used
+ for comments. Add a backslash ("`\`") to the beginning of the
+ pattern if it starts with a hash.
+
+ - Each other line contains a single pattern.
+--
++
+Patterns have the same syntax and semantics as patterns used for
+fnmantch(3) without the FNM_PATHNAME flag, except a pathname also
+matches a pattern if removing any number of the final pathname
+components matches the pattern. For example, the pattern "`foo*bar`"
+matches "`fooasdfbar`" and "`foo/bar/baz/asdf`" but not "`foobarx`".

-R::
--inter-hunk-context=<lines>::
Show the context between diff hunks, up to the specified number
of lines, thereby fusing hunks that are close to each other.
+ Defaults to `diff.interHunkContext` or 0 if the config option
+ is unset.
-W::
--function-context::
--no-prefix::
Do not show any source or destination prefix.
+--line-prefix=<prefix>::
+ Prepend an additional prefix to every line of output.
+
+--ita-invisible-in-index::
+ By default entries added by "git add -N" appear as an existing
+ empty file in "git diff" and a new file in "git diff --cached".
+ This option makes the entry appear as a new file in "git diff"
+ and non-existent in "git diff --cached". This option could be
+ reverted with `--ita-visible-in-index`. Both options are
+ experimental and could be removed in future.
