forked from Mirrors/wine-wine
ucrtbase: Implement the new printf corner case behaviour.
Check the option flags whether the new or old legacy behaviours are wanted. For _MSVCR_VER < 140, don't check the option flags but hardcode them to TRUE. (This avoids having to manually add all three flags into every caller of pf_printf.) Mask out any other flags, to avoid other out-of-range flags to be interpreted as the other flags (positional params, invoke invalid param handler).
