-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, instead of showing pairwise diff between
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
from each of the parents to the merge result simultaneously
instead of showing pairwise diff between a parent and the
result one at a time (which is what the '-m' option does).
Furthermore, it lists only files which were modified
from all parents.
-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
hunks disappear, the commit itself and the commit log
message is not shown, just like any other "empty diff" cases.
