Do you then take this as being length modifier 'h' followed by format
specifier 's', or is it a complete specifier on its own with everything
that would otherwise be length and specifier being reparsed as an
extension if it can't be parsed as a standard format? Do the flags "-wp"
and "cR" for %s formats apply to this format?
