It is not orthogonal to --push in the config, but the behavior exposed
to the user is orthogonal unless I am missing something?

I can understand that --fetch sounds a bit weird, what about this
natural translation:

    "git remote: set the URL (only the fetch one) for NAME to URL"
    git remote set-url --only=fetch NAME URL

    "git remote: set the URL (only the push one) for NAME to URL"
    git remote set-url --only=push NAME URL
    (obsoletes --push)

    "git remote: set the URL (both) for NAME to URL"
    git remote set-url --only=both NAME URL
    (it would be nice if --only=both (weird!) can be removed in the
    future such that the option is more natural)

    "git remote: set the URL for NAME to URL"
    git remote set-url NAME URL
    (current behavior: YOU git guru knows what I do right?)

A transition period would also help to solicit feedback.

I prefer 1 for now as it avoids the extra manual action I have to take
when changing URLs.
