You're not applying the "string syntax class", but the "word syntax-class".

                   ^^                                                ^^
Again, these backslashes will be ignored.

The issue of what to do with "foo(bar)baz)" is still open.

> +      (add-text-properties
> +       (match-beginning 1) (match-end 1)
> +       '(syntax-table (2) font-lock-face font-lock-string-face)))))

The downside of this approach is that M-f, M-b will skip over the whole
URL rather than go one word at a time.
