If merging results in an unchanged tree, git-commit-script should not complain that there's nothing to commit. Also, add "[--all]" to usage(). [jc: usually there is no reason to record an unchanging merge, but this code path is triggered only when there is a nontrivial merge that needed to be resolved by hand, and we should be able to record the fact that these two tree heads are dealt with as a regular two-parent commit in order to help later merges.] Signed-off-by: Junio C Hamano <junkio@cox.net>
