--histogram::
Generate a diff using the "histogram diff" algorithm.
+--diff-algorithm={patience|minimal|histogram|myers}::
+ Choose a diff algorithm. The variants are as follows:
++
+--
+`default`, `myers`;;
+ The basic greedy diff algorithm. Currently, this is the default.
+`minimal`;;
+ Spend extra time to make sure the smallest possible diff is
+ produced.
+`patience`;;
+ Use "patience diff" algorithm when generating patches.
+`histogram`;;
+ This algorithm extends the patience algorithm to "support
+ low-occurrence common elements".

++
+For instance, if you configured diff.algorithm variable to a
+non-default value and want to use the default one, then you
+have to use `--diff-algorithm=default` option.

--stat[=<width>[,<name-width>[,<count>]]]::
- Generate a diffstat. You can override the default
- output width for 80-column terminal by `--stat=<width>`.
- The width of the filename part can be controlled by
- giving another width to it separated by a comma.
+ Generate a diffstat. By default, as much space as necessary
+ will be used for the filename part, and the rest for the graph
+ part. Maximum width defaults to terminal width, or 80 columns
+ if not connected to a terminal, and can be overridden by
+ `<width>`. The width of the filename part can be limited by
+ giving another width `<name-width>` after a comma. The width
+ of the graph part can be limited by using
+ `--stat-graph-width=<width>` (affects all commands generating
+ a stat graph) or by setting `diff.statGraphWidth=<width>`
+ (does not affect `git format-patch`).
By giving a third parameter `<count>`, you can limit the
- output to the first `<count>` lines, followed by
- `...` if there are more.

These parameters can also be set individually with `--stat-width=<width>`,
`--stat-name-width=<name-width>` and `--stat-count=<count>`.
--numstat::
- Similar to `\--stat`, but shows number of added and
+ Similar to `--stat`, but shows number of added and
deleted lines in decimal notation and pathname without
abbreviation, to make it more machine friendly. For
binary files, outputs two `-` instead of saying
of the `--diff-filter` option on what the status letters mean.
--submodule[=<format>]::
- Chose the output format for submodule differences. <format> can be one of
- 'short' and 'log'. 'short' just shows pairs of commit names, this format
- is used when this option is not given. 'log' is the default value for this
- option and lists the commits in that commit range like the 'summary'
- option of linkgit:git-submodule[1] does.
+ 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.
--color[=<when>]::
Show colored diff.
- The value must be `always` (the default for `<when>`), `never`, or `auto`.
- The default value is `never`.
+ `--color` (i.e. without '=<when>') is the same as `--color=always`.
+ '<when>' can be one of `always`, `never`, or `auto`.

+ a fraction, with a decimal point before it. I.e., `-M5` becomes
+ 0.5, and is thus the same as `-M50%`. Similarly, `-M05` is
+ the same as `-M5%`. To limit detection to exact renames, use
+ `-M100%`.
