Thanks, both of you.

The correct way to quote $words[1] would have been «${(q)words[1]}», but
elements of $words are already command-line quoted so they don't need to
be quoted again.  That is: just using $words[1] directly would be correct.
(modulo noglob, but don't worry about that)

Since the patch was broken by your mailer, I'm reincluding it here so
it's easier to review/apply.  (You can usually send patches as
attachments named *.txt to prevent munging and ensure a sane MIME type.)

workers@: I've added this to my list to review, but my list is quite full
nowadays, feel free to beat me to applying this.

Thanks again for the patch.

Cheers,

Daniel
