My recommendation is to allow both "git --merge-base A..B" and "git
--merge-base A...B".  The discussion about A..B and SWAP() would
equally apply to builtin/diff part of the patch.  The posted patch
ignores the swap logic when --merge-base is given, but we should
apply the swap logic first and then make sure the merge_base logic
will have the oid[0] and oid[1] in the correct order.
