It's hard to know what to do.  You don't expect to be able to set an option
only when a module is loaded, so I don't think we can have module-dependent
options.  But zle related options are in the main shell even if zle isn't
loaded.  Maybe we just have to make it an option (menuselect, obviously)
anyway and make a bigger effort to load complist when necessary, so you
would get an error from completion the first time if it's not available.

Also, we should definitely change zmodload to be able to list builtin
modules, which means adding a reduced version of zmodload even for shells
without dynamic linking.  It's getting too inconvenient not to have the
information available in functions.  Two possibilities are

- zmodload lists all modules, whether builtin or not, but marks the builtin
  one differently -- this makes it harder if you want to check $(zmodload)
- some new options will list all modules or builtin modules.  This is
  probably better but the problem is that with a non-dynamically-linked
  shell you always get no output from running `zmodload' on its own which
  is a little Zen-like.  Maybe it should return status 1 in that case as a
  test for dynamic loading, but status 0 when the list includes builtin
  modules.

And I still think the zle command needs the ability to list builtin
widgets, too.

One other thing:  I'm still a bit worried about the way undo works, where
the first time nothing happens if there isn't a suffix to undo.  It's fine
if there is a suffix which you can undo separately, but I'd be tempted to
make it skip over that if it does nothing.  That would make it harder if
you used undo in programming, however, but I don't think people do.

I've done this and I'll try and get pws-$((N+1)) out at the end of the
week, particularly since I'm busy next week.  There were some other minor
changes:  a tt(no) in the manual was missing a close parenthesis, some
dependencies for mod_complist.yo needed adding in the Makefile, a nodref
referred to `The complist module' instead of `The complist Module'.  These
are appended below, but it assmues the name changes.
