... and by the time the completion script knew what they are, we
have all information necessary without actually having the user run
the command ;-)  That does sound backwards.

I am however not sure what Szeder really meant by "refnames".  For
example, you may want to see that this

	$ git ls-remote origin mast<TAG>

peek into refs/remotes/origin/* and find those matching, i.e. most
likely "master", and that can be done without talking to the remote
side.  It won't catch the case where the remote end added a new
branch that also match, e.g. "mastiff", and it will actively harm
the users by giving the impression that Git (collectively, even
though from technical point of view, what the completion script does
is not part of Git) told them that there is no such new branch they
need to worry about.

So probably even with the "peek local" optimization, I have a feeling
that completion of refnames may not be such a good idea.
