$ emacs --batch -batch; echo $?
Unknown option `-batch'

Same problem for --no-window-system -no-window-system. It doesn't
occur for all options though, e.g. --no-init-file -no-init-file
doesn't cause an error.

This is an issue mainly when calling Emacs from a Makefile, where
options from several variables (like AM_ELCFLAGS and ELCFLAGS) can be
accumulated.

Also emacs --bat --batch.  sort_args in emacs.c can only remove
duplicates that match exactly.  All arguments handled in main are
affected.
