a cut-off percent (3% by default) are not shown. The cut-off percent
can be set with `--dirstat=<limit>`. Changes in a child directory are not
counted for the parent directory, unless `--cumulative` is used.
++
+Note that the `--dirstat` option computes the changes while ignoring

+rearranging lines in a file is not counted as much as other changes.
--dirstat-by-file[=<limit>]::
Same as `--dirstat`, but counts changed files instead of lines.
--color[=<when>]::
Show colored diff.

--no-color::

--word-diff[=<mode>]::

+ If `n` is specified, it is a threshold on the similarity
index (i.e. amount of addition/deletions compared to the
file's size). For example, `-M90%` means git should consider a
delete/add pair to be a rename if more than 90% of the file
projects, so use it with caution. Giving more than one
`-C` option has the same effect.
+-D::

+When used together with `-B`, omit also the preimage in the deletion part
+of a delete/create pair.

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