I think this is actually the same as the (very long) bug#57752, so 
thanks for working on this. (It was on my list of things to get to, but 
I just haven't had time.)

Over there, we agreed that something like your patch is wanted, albeit 
with two caveats:

1. Since "--funcall" for the regular "emacs" binary doesn't pass 
arguments to the function, how about we call this option "--apply" instead?

2. It would be great if we could get "--apply" for the regular "emacs" 
binary too, so that both programs work the same way (at least in this 
regard). Even better, if you could forward "--apply" from "emacsclient" 
to the alternate editor (which would be "emacs" 99% of the time) 
automatically. That works, in a roundabout way, for the Emacs daemon, 
but not if the alternate editor is "emacs".
