FreeBSD has, of course, accepted the uppercase letters as synonyms since
r132933 (July of 2004).  It seems that while Mac OS (at least on the High
Sierra I have handy) only accepts the minuscule 'm', Linux will only
accept the majuscule 'M' (!).

So it's probably more appropriate to make a note about the argument not
being fully portable than to try to adjust the example to work everywhere.
