The code in that function seems to indicate that S_IF* isn't POSIX.
Not having a copy of POSIX.1 (and the library here won't open for a
while :-(), can someone confirm that this is the case?  Should the code
be rewritten to use the (ugly, less efficient) S_IS* macros?

I'd like them all to use the same letter, and was rather disappointed
to see that typeset -L is taken.  -L is a very obvious, quite intuitive
choice, so personally I'd be prepared to have an exception.  I would
probably have chosen -Q.

If we want them *all* to be the same letter, the possibilities are -J,
- -M, -U, -V, -W, -Y, -w and -y, assuming -Q is taken by compctl.  (Hmm,
I hope we don't start needing to use digits for compctl, it's terribly
ugly (why did we do that with zsh's command line options?))  None of
these is anywhere near as good as -L; can someone come up with a
rational reason to pick one of them?  Perhaps -M for coMMands?

I don't think so.  Most of the listing code is there already -- I'll
just need to add a little code to output in a different format.  It's a
fundamentally simple addition.  Anyway, I'll wait for the next beta
before writing this stuff.
