I am a bit unhappy that subsequent fetches have to re-read the
remote config every time.  I can sort-of-see we can cram the
"this is expected to be rewound" information as part of
peek-remote exchange to avoid the overhead, but I do not think
it is easily doable for dumb transports without breaking the
backward compatibility.

Perhaps below the "Pull: refs/heads/*:refs/remotes/origin/*" (or config
equivalent) we should list (in some format) branches which are not to be
fetched becaus they don't fast forward. One option, namely
  Pull:-refs/heads/pu:refs/remotes/origin/pu
(or config equivalent)comes to mind. It has the advantage that when we
decide to fetch this branch, it would be as easy as changing '-' to '+'.
Or we can use '!' instead of '-' if you think it is more readable (probably
is).
