But I don't think there are more than 8 actual legal qualifiers. And 'base' could be just 2 bits, since there are only a couple of legal bases, but I left room for them all anyway. And the other really should fit in those numbers unchanged, I think.

We do need one special value for the "no > width, no precision", though. Btw, yeah, we do have a couple of "%.100s" etc, but we could fix those if we really wanted to do this. And no, I guess we don't really need to make it 32-bit. Fitting in 64 bits would already be a big improvement over what we have now.
