Subject: [PATCH] printf: In d/i/o/u/x/X conversions with a precision
 specified, the 0 flag should be ignored.

For example, the output of the following should have only two leading zeros (and the rest of the field width padded with spaces):

#include <stdio.h>

int main(void) {
        printf("%016.5i\n", 123);
}
