--patience::
Generate a diff using the "patience diff" algorithm.
---stat[=<width>[,<name-width>]]::
+--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.
+ By giving a third parameter `<count>`, you can limit the
+ output to the first `<count>` lines, followed by
+ `...` if there are more.
--numstat::
Similar to `\--stat`, but shows number of added and
projects, so use it with caution. Giving more than one
`-C` option has the same effect.
+-D::
+--irreversible-delete::
+ Omit the preimage for deletes, i.e. print only the header but not
+ the diff between the preimage and `/dev/null`. The resulting patch
+ is not meant to be applied with `patch` nor `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
+ enough information to apply such a patch in reverse, even manually,
+ hence the name of the option.
++
+When used together with `-B`, omit also the preimage in the deletion part
+of a delete/create pair.

-l<num>::
The `-M` and `-C` options require O(n^2) processing time where n
is the number of potential rename/copy targets. This
