Yes, that sounds good.  (But we'd still need "--" to say that the
arguments have ended.)

I think that sounds more obscure, really (even if it's simpler to
implement in the "emacs" case).

Since we have to add something new to emacsclient in any case, I'd
rather go with adding "--apply" to both Emacs and emacsclient, I think.
