I think you can put the "-" on the end of the line like this:
  _wanted ... \
     _files -W ${ODMDIR:-/etc/objrepos} -g '^*.vc' "$@" -

That's a slightly unusual case because any matches passed to
_sub_commands could be thought of as not being arguments to compadd to
be passed on in the traditional sense. It is probably best handled by
passing a "-" in the calling function.

I agree that this isn't particularly ideal though. I remember Sven
saying something about rethinking the way compadd options are passed
but I was mostly thinking in terms of suffixes and not descriptions.
It'd be wise to think in terms of all the compadd options and how they
are passed around in coming up with a good solution.

A variant of your _all_labels suggestion is perhaps not a bad idea. I'd
want to be able to override any passed descriptions in some cases.
