+-c::
+       This flag changes the way a merge commit is displayed
+       (which means it is useful only when the command is given
+       one <tree-ish>, or '--stdin').  It shows the differences
+       from each of the parents to the merge result simultaneously

+-cc::
+       This flag changes the way a merge commit patch is displayed,
+       in a similar way to the '-c' option. It implies the '-c'
+       and '-p' 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.  When this optimization makes all
