Remove redundant printf tests

Browse Source 
%.0i and %.0u take the same path as %.0d because 'i' and 'u' are normalized
to 'd', the uppercase variants only set the upper flag which is unobservable
when there are no digits, and %-5.0d cannot be distinguished from %5.0d
because the output is empty.
