PATCH: 3.1.5-pws-7: compctl -LM

[Peter Stephenson <pws@ibmth.df.unipi.it>]

This is fairly trivial, but it seemed to me that `compctl -LM' should
work in the obvious way --- am I right that at the moment you have to
grope it out of a full compctl -L ?.  The catch is that `compctl -M -L'
also works in the obvious way, but it's a different way.  At least you
get an error message in the second case.  Most of the code for this is
already there.
