From: Yann Dirson <yann.dirson@xxxxxxxxx>
So we now have -O, similar to the existing option in stg diff, to pass
flags to git-diff when computing the 2 diffs to compare (-M, -C and -w
come to mind as being potentially useful here), and -o can be used to
tune the invocation of diff on those 2 diffs.
Note that -o is only there temporarily, and will disappear when a more
sophisticated process than plain diff will be used.
