 	Tells `git-apply` how to handle whitespaces, in the same way
 	as the '--whitespace' option. See gitlink:git-apply[1].
 
+diff.color::

+	colors only when the output is to the terminal.

+diff.color.<slot>::
+	Use customized color for diff colorization.  `<slot>`

+	color, and is one of `plain` (context text), `meta`

+	lines), or `new` (added lines).  The value for these

 diff.renameLimit::
 	The number of files to consider when performing the copy/rename
 	detection; equivalent to the git diff option '-l'.
 
+diff.renames::
+	Tells git to detect renames.  If set to any boolean value, it
+	will enable basic rename detection.  If set to "copies" or
+	"copy", it will detect copies, as well.
+
 format.headers::
 	Additional email headers to include in a patch to be submitted
 	by mail.  See gitlink:git-format-patch[1].
