When encountering an option not described by the specs, `zparseopts -F`
prints an error message with the first character following the leading
'-'.  This works great for short options, but for long options it leads
to the uninformative message "bad option: -".

I see that this was the original intended behaviour in the V12zparseopts
tests, so ignore if I've missed something.
