I think there's a bit of crosstalk-- as I read it, Miles wants to avoid
creating the tmp even when diff has output, because renames are
expensive on NFS.
That would mean going straight to the final filename when producing
changesets. But I haven't looked at the code, so I don't know whether
that's practical or not.
