+-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

+
+--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 in any other "empty diff" case.
+
+--always::
+	Show the commit itself and the commit log message even
