That's true in elisp-mode, but in html-helper-mode parentheses are
highlighted blue and this overwrites the green.  But that's okay... not

That did it.  Works perfectly now.  On Emacs 21.  Guess I should save
the previous defs for when I upgrade.

(Note: I wanted "???"-- without the quotation marks-- highlighted.
That's what I get now.)
