Using log-tree traversal machinery instead of just get_revision()
would probably mean we would slow it down quite a bit unless we are
careful, but at the same time, things like "git shortlog -G<string>"
would suddenly start working, so this is not just helping the
"--follow" hack.

I didn't notice that, but I'm not surprised that there are more options
that shortlog doesn't quite work with.

I don't plan on working on this myself any time soon, so maybe it's a
good #leftoverbits candidate (though it's perhaps a little more involved
than some).

I agree that I do not mind seeing those who haven't really touched
the inner core of the system to try this change, so marking this
discussion with #leftoverbits may be a good idea, but I have this
gut feeling that "a little more involved" might be a bit of an
understatement ;-)

But still I think it is a very good suggestion to allow log-tree to
filter things more so that "shortlog $args" can become a more
faithful imitation of "log $args | shortlog".

Thanks.
