-J and perhaps also -V, -E, -1 and -2. It'd be hard to know which to
check for.

There are cases where you do want to override any passed descriptions
such as where a function completes something in parts (e.g. in _urls)
but you might want to pass on other options. I'm not too sure about
your suggested change to _all_labels because the result would be less
flexible. If you wanted a solution like that, it might be better to
always add explanations to the end of the options unless some option
was passed to _all_labels. I think the current system is simpler but
will concede that modifying all the functions will be a bore. I'll
volunteer for the job if we agree on doing that though.

Quite a few functions accept non compadd options though zparseopts can
easily strip them before they get passed to compadd. Provided they
don't conflict, I don't see a problem with this.
