This change fixes all the cases in this thread, and passes all zsh tests and
all z-sy-h tests (which rely heavily on ${(z)} functioning correctly); however,
I don't know whether it's correct.

I'm guessing that the different meaning of parentheses are being confused for
each other:

- Array assignment
- End of subshell
- Function defnition
- Glob qualifier

Thanks,
