+ This flag changes the way a merge commit is displayed

one <tree-ish>, or '--stdin'). It shows the differences
- from each of the parents to the merge result

- a parent and the result one at a time, which '-m' option
- output does. '--cc' further compresses the output by
- omiting hunks that show differences from only one

+ result one at a time (which is what the '-m' option does).
+ Furthermore, it lists only files which were modified

+-cc::
+ This flag changes the way a merge commit patch is displayed,

parent, or show the same change from all but one parent
for an Octopus merge. When this optimization makes all
