I'd been wondering if the usual Euclidean algorithm guaranteed that
already, or something like it, so all we would have to do is document
what the current code does :-).
The only thing to be careful of is not to specify something that might
be hard to implement in the future. But I expect once one has u,v
roughly in the vicinity of a,b then any sensible rule can be applied
with not much work, certainly not much compared to getting there in
the first place.
Please don't specify something just for the uniformity of mpn.
Uniformity isn't an important design goal of mpn. Speed, though,
