} I'm on the case, but just to note this isn't completely benign.  There
} are (few) places in functions where we rely on the fact that anything in
} parentheses is parsed as a single quoted string, which won't happen any
} more.

Hm.  It appears we always parsed this "correctly" when using the old style
case statment:

torch% case "foo bar baz" in
case> foo bar *) echo here;;
zsh: parse error near `bar'

So perhaps the most benign thing is to apply the word parsing inside the
matched parens only in some sort of POSIX mode?

} I don't want to have to propagate the
} existing hack any more, however, so this isn't really possible to work
} around.

Urm.  OK.
