The '%' character in a format specification may be followed by one or more flags from the list "+- #0". BusyBox printf didn't support the '0' flag or allow multiple flags to be provided. As a result the formats '%0*d' and '%0 d' were considered to be invalid. The lack of support for '0' was pointed out by Andrew Snyder on the musl mailing list: https://www.openwall.com/lists/musl/2021/12/14/2 function old new delta printf_main 860 891 +31 .rodata 99281 99282 +1 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 2/0 up/down: 32/0) Total: 32 bytes Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
