I think I'm missing something.  Why wouldn't "ls-refs for push" not pass
the information that it's for push as part of the *body* of the ls-refs
request?

(That's a separate issue from whether we need to have ls-refs for push
at all, as opposed to specifying a policy for the requested ref
updates and getting a list of "have"s without ref names attached.  But
that's a discussion for another day.)

Is there some other more immediate motivation for this patch?  In the
spirit of YAGNI, I would rather understand that motivation instead of
one that in many possible designs would never materialize.

Thanks,
Jonathan
