This had bit-rotted quite a bit, so I've rebased it on top of today's master.

There's not really any other changes to speak of. I've not reevaluated
the patch to see if there is any more simple way to take care of this
problem yet. However, I do recall getting off to quite a few false
starts with this patch and the way I have it now was the only way I
saw to make it possible. Although, perhaps some more experience will
show me something different.

Anyway, I've attached the rebased version.
