--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. By default, as much space as necessary
will be used for the filename part, and the rest for the graph
--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`.

If `n` is specified, it is a threshold on the similarity
index (i.e. amount of addition/deletions compared to the

delete/add pair to be a rename if more than 90% of the file
hasn't changed. Without a `%` sign, the number is to be read as
a fraction, with a decimal point before it. I.e., `-M5` becomes

Ignore changes to submodules in the diff generation. <when> can be
