Fix multiple sign'edness issues; for %width.prec variables, neither
is -ever- signed, we pull out -width as a flag, and prec is folded +.
Changing the code only required special handling of %*.* variables,
continuing to read them as int, and preserving the folding of negative
values that's already there.
