Option letters

The documentation-only patch below adds an alphabetical option listing
to the zshoptions man page.  I find it quite helpful.

(On the subject of man pages, is it *really* necessary for zshall.1 to
contain the full path to the man pages?  ".so man1/zshfoo.1" works fine
with all versions of man that I've seen, and having the full path is
really quite inconvenient at times.)

To the point... I'm adding a -M option to a number of builtins.  I'd
like to add one to {,un}setopt, but that would clash with the current
meaning of -M, which is the SINGLE_LINE_ZLE option.  It already has a
special meaning for -m, clashing with MONITOR, so I suppose it should
be OK to use -M.  Does anyone have an opinion on the matter?  What
about set, which currently doesn't have any such clashes?
