Nice---this will later lets us do push.atomic if we really wanted
to, right?

Yeah, that part of the push callchain always confuses me every time
I look at it.  I think it was a consequence of how transport layer
was wedged into the existing codepath that only handled push that
called send-pack to unify the codepaths that push calls into
different transport backends, and we may have done it differently
and more cleanly if we were designing the push to transport to
backends from scratch.
