Ugh, hit send too soon. I meant to close with the observation that it
may be safe to rely on strcoll() / strxfrm() + strcmp() not ever
returning 0 on certain platforms, if my inability to recreate this is
anything to go by. There could be a test run by configure that
determines this, enabling us to then use the strxfrm() optimisation.
