Output the distribution of relative amount of changes (number of lines added or

Same as `--dirstat`, but counts changed files instead of lines.

+--break-rewrites[=[<n>][/<m>]]::
+ Break complete rewrite changes into pairs of delete and

+It affects the way a change that amounts to a total rewrite of a file
+not as a series of deletion and insertion mixed together with a very
+few lines that happen to match textually as the context, but as a
+single deletion of everything old followed by a single insertion of
+everything new, and the number `m` controls this aspect of the -B
+option (defaults to 60%). `-B/70%` specifies that less than 30% of the
+original should remain in the result for git to consider it a total
+rewrite (i.e. otherwise the resulting patch will be a series of
+deletion and insertion mixed together with context lines).
++
+When used with -M, a totally-rewritten file is also considered as the
+source of a rename (usually -M only considers a file that disappeared
+as the source of a rename), and the number `n` controls this aspect of
+the -B option (defaults to 50%). `-B20%` specifies that a change with
+addition and deletion compared to 20% or more of the file's size are
+eligible for being picked up as a possible source of a rename to
+another file.

Detect renames.

For following files across renames while traversing history, see
`--follow`.

--C::
+ If `n` is specified, it is a is a threshold on the similarity

Detect copies as well as renames. See also `--find-copies-harder`.

For performance reasons, by default, `-C` option finds copies only
