Something like the patch below (which is obviously missing all of the
infrastructure for doing this optionally, but is meant to illustrate
what I'm talking about).
The downside of this is that it only works for the git protocol
transport, making dumb push even more of a second class citizen (it
looks like this is already the case for updating tracking refs). But I
think this is the right place to do it, since we have detailed
information on the matched refs. If other transports want to do the same
thing, we should abstract setup_tracking (and update_tracking_ref while
we're at it) and call them from those transports.
