I'll bet this is exactly the same bug I described back in April:
    http://www.zsh.org/mla/workers-1998/msg00178.html
    http://www.zsh.org/mla/workers-1998/msg00180.html

The context (a builtin piped to an external with a $(...) argument) is
certainly exactly the same.

And indeed, with your patch applied to 3.0.5 (it applies fine with fuzz)
I'm unable to repeat the bug describe in msg00178.html.  In a version of
3.0.5 that does NOT have your patch, I can repeat the bug within five or
six tries.

Thanks for the patch!
