OK, I've attemped to do that in the attached. I'm pretty sure I didn't
get all of the overflows right, so someone should probably take a really
good look at it. (I'm not too confident the original code got them
right either, but whatever).

Speaking of good looks, should I add it to the next commitfest as a new
patch, or should we try and get someone to review it like this?

I've left this question unanswered for now. We can fix it later,
independently of this patch.
