For a simpler case that would work, but because we are not saving
just a patch but two full trees to compare (i.e. merge-fix/$this-$that
is the postimage, its ^1 is the preimage), you should be able to use
the three-way merge in a similar way cherry-pick works. In fact, that
is how rerere replays the recorded resolution, not with a "patch -p1".
