OK: It gradually builds up a merge from several small ones using
different strategies.

But after a merge, 'git log emacs-24 ^master' should be empty, just like
'bzr missing ../emacs-24 --theirs-only' was empty, right?  You cannot
achieve that with the 'ours' strategy, since it will not be the same
commit anymore.
