M option on sort

[Phil Hughes]

While working on a new class I noticed the -M option of sort -- compare
as months.  The system 5 and and XENIX 5 documentation list this but
do not include it as an option that can be used with specific keys.
This seemed absurd so I tried it (e.g., sort +1M -2 +3 -4 file) and
it seems to work fine on XENIX 5. 

We publish a series of references for various UNIX flavors.  I would
like to get the "facts behind the rumors" for this option so it could
be corrected in our pocket references.
