[PATCH] git-merge-cache -q doesn't complain about failing merge program
git-merge-cache reporting failed merge program is undesirable for
Cogito, since it emits its own more appropriate error message in that
case. However, I want to show other possible git-merge-cache error
messages. So -q will just silence this particular error.
