Of course, I tried, but couldn't get it to work. I get HEAD and top
not equal unless I call update() between _TransPatchMap and
self.__halt(). For the non-conflicting case we need to call update
before or after this "if merge_conflict".

One solution is to split the "if merge_conflict" in two but maybe you
have a better idea.
