It seems like you could just do an elongated fetch. So you first fetch
the current tip, then after you have it, you see what other data you
need, and send that along.

Certainly we already do that in bzr for fetching inventories chaining to
chk_bytes chaining to file texts.

I don't know the bzr-hg internals, but conceptually it doesn't seem like
we would have to know all the tags up front.
