bug#5392: 23.1.91; -Q becomes unknown if -displat is given.

Start emacs:
% emacs -Q -display :0

A message appears in the minibuffer: Unknown option -Q.
This is from command-line-1.  -Q has not been handeled since
sort_args seems to always put -display before -Q (and others) handled
in startup.el.  Thus the handling of option stops when -display is seen
and -Q gets passed to command-line-1, which chould not happen.

I don't understand the comment in emacs.c:
  /* -d must come last before the options handled in startup.el.  */
  { "-d", "--display", 60, 1 },
  { "-display", 0, 60, 1 },

Changing the prio to 6 cures this bug, but the comment seems to indicate
this is the wrong thing to do.
