        This flag implies the '-c' options and further compresses the
-       patch output by omitting hunks that show differences from only
-       one parent, or show the same change from all but one parent for
-       an Octopus merge.
+       patch output by omitting uninteresting hunks whose contents in
+       the parents have only two variants and the merge result picks
+       one of them without modification.
