After starring at it for some time, the best solution I could come up
with is this:

--8<---------------cut here---------------start------------->8---
diff --git a/font-latex.el b/font-latex.el
index b78cf58a..e9bce29c 100644
--- a/font-latex.el
+++ b/font-latex.el

                   ;; Some macros take an optional argument.  This is
                   ;; the same line as above for environments.
                   "\\(?:\\[[^][]*\\(?:\\[[^][]*\\][^][]*\\)*\\]\\)?"
-                  "\\({\\).*?[^\\]\\(?:\\\\\\\\\\)*\\(}\\)")
-         (1 "|") (2 "|")))))
+                  ;; "\\({\\).*?[^\\]\\(?:\\\\\\\\\\)*\\(}\\)"

+                  "\\(" (regexp-quote TeX-esc) "*\\)"
+                  "\\(}\\)"
+                  )
+         (1 "|") (2 ".") (3 "|")))))
   (when font-latex-syntactic-keywords-extra
     (nconc font-latex-syntactic-keywords font-latex-syntactic-keywords-extra))
   ;; ;; Cater for docTeX mode.
--8<---------------cut here---------------end--------------->8---

It still doesn't solve the issue Al has `rainbow-delimiters` (I guess),
but should unbreak the fontification and give somewhat better results.

@Al: Do you want to give it a roll?

Best, Arash
