Sorry, I think I confused you, please post that patch here. This issue is for documenting the workarounds, issue 9338 is for actually solving the problem.

I glanced at your patch on that issue, and it looks basically okay, though I'd like to see a few more tests for the help messages to cover things like:

   -x X A                       # no --
   -x [X [X ...]] -y Y [Y ...]  # no --
   -x [X] -- A B                # needs --
   -x X [X ...]                 # needs --
   -x [X [X ...]]               # needs --

It's possible the first two are already covered by the other tests, but at least the last three should all be tested for.
