-C::
Detect copies as well as renames.
+--diff-filter=[ACDMRTUXB*]::
+ Select only files that are Added (`A`), Copied (`C`),
+ Deleted (`D`), Modified (`M`), Renamed (`R`), have their
+ type (mode) changed (`T`), are Unmerged (`U`), are
+ Unknown (`X`), or have had their pairing Broken (`B`).
+ Any combination of the filter characters may be used.
+ When `*` (All-or-none) is added to the combination, all
+ paths are selected if there is any file that matches
+ other criteria in the comparison; if there is no file
+ that matches other criteria, nothing is selected.
+
--find-copies-harder::
For performance reasons, by default, -C option finds copies only
if the original file of the copy was modified in the same
