It does, but as I mention in the other reply, I don't think we want this,
since the user used a valid option argument (ie, "native") and we don't
want to give a "hint" as a valid option, since their option was valid.
Like I said in the other reply, I think we do want the code the patch
showed.

Either that, or I could still call candidates_list_and_hint() and just
throw the hint away, since it's meaningless.
