+                Patch files are files whose names usually end in
+                <filename>.patch</filename> or <filename>.diff</filename> but
+                can end with compressed suffixes such as
+                <filename>diff.gz</filename> and
+                <filename>patch.bz2</filename>, for example.

                 in the
