\} parse error in 3.0.3-test4

[Roderick Schertler]

Here's a parse error in 3.0.3-test4 which wasn't in 3.0.2:

    $ zsh-3.0.2 -fxc 'eval last=\$\{$#\}' foo bar
    + eval last=${1}
    + last=bar

    $ zsh-3.0.3-test4 -fxc 'eval last=\$\{$#\}' foo bar
    + eval last=${1
    foo: closing brace expected

It doesn't happen if you use quotes rather than a backwhack.

    $ zsh-3.0.3-test4 -fxc 'eval last=\$\{$#"}"' foo bar
    + eval last=${1}
    + last=bar

Fix is included below.  This should be applied to zsh-3.0.3-test4 and
zsh-3.1.1.
