Interesting.

I briefly wondered if the update_files() in the middle may be
prevented by D/F conflict if you didn't remove the path beforehand,
but path and new_path are both in the same directory, so that would
not be the reason.  Checking out 51931bf and running two tests (6022
and 6042) that were modified to protect the fix after applying this
partial revert does not seem to break, either, so...
