regexp-opt-group is a compiled Lisp function in `regexp-opt'.
(regexp-opt-group STRINGS &optional PAREN LAX)
Return a regexp to match a string in STRINGS.

(regexp-opt-group '("000" "this string is missing" "foo"
"0this occurs twice"))
==>

"0\\(?:00\\|this occurs twice\\)\\|foo\\|0this occurs twice"

This isn't correct, is it (GNU Emacs 21.2.1)?
