Sounds like a good idea. How about something like the following?

It isn't really interesting to know about the renames that have
already been committed to the branch you are working on. Furthermore,
the 'git-apply --stat' at the end of git-(merge|pull) will tell us
about any renames in the other branch.

With this commit only renames which require a file-level merge will
be printed.
