I don't know offhand. OBSD's getopt() is different than GNU's, which has
a way to indicate that arguments to options are themselves optional (two
colons in the optstring). I should get back to work, so I'll let you
re-read the manual page. :)

Yes: 16 and 0xF are two representations of the same value. As for what
your value range is, I'd say that since Unix files are streams of bytes,
the range is that of an unsigned char: from 0 to 2 ** 8 (0 -> 256 or
0x00 -> 0xFF).
