What is the result of: printf("%#.4o", 345);? Is it 0531 or is it 00531?
Subclause 7.9.6.1, on page 132, lines 37-38 says: “For o conversion, it
increases the precision to force the first digit of the result to be a zero.”
Is this a conditional or an unconditional increase in the precision if the most
significant digit is not already a 0? Which is the correct interpretation?
Comment from WG14 on 1997-09-23:
In subclause 7.9.6.1, page 132, lines 37-38, change:
For o conversion, it increases the precision to force the first digit of the
result to be a zero.
to:
For o conversion, it increases the precision, if and only if necessary, to
force the first digit of the result to be a zero.
