I didn't suggest to do them both in one go, I suggested that invoking
"C-x v v" _after_ the one that committed a changeset will either push
or offer pushing as one of a small number of possible actions.

What is reasonable after a commit?  Either (a) show or (b) push or (c)
another commit or (d) pull.  So why not ask the user which one of
these would he/she want to do?  We could even try to be smart about
that: for example, if the clone is ahead of upstream, push might be
the moist reasonable possibility.

What does "C-x v v" do today after push?  If the tree is clean,
nothing useful.  So what are we going to lose?

For that reason, I never pull before pushing, unless push tells me I
must.
