Zero padding disabled when precision specified

[Iangitpers]

An issue I've noticed:
c=29;
printf("%03.u", c);
Output: " 29"
Expected "029"

In v4 around line 724:

       // ignore '0' flag when precision is given
        if ((flags & FLAGS_PRECISION)) {
          flags &= ~FLAGS_ZEROPAD;
        }

A hack:

       // ignore '0' flag when precision is given
        //HACK: we want the leading 0s with precision....
        if ((flags & FLAGS_PRECISION) && (*format != 'u')) {
          flags &= ~FLAGS_ZEROPAD;
        }

"%03.u"
You have specified the 0 flag and a width of 3, followed by an incomplete precision (no digits after the .)
Standard behavior is to ignore the 0 flag when precision is specified.
If you want a precision of 3, your string should be "%.3u", if you want a width of 3, your string should be "%03u", both will produce the same output for unsigned integer types.
