If people are really interested, I think I have enough data in my db to
extract this kind of information.  The code to implement it would take a
little while to muck through, though, and right now I have a bunch of
other irons in the fire.

I've also done some prototype work for "show last commit by or on
behalf of committer" but it relies on CVS logs which are not guaranteed
to really be inclusive.
