Just a wild guess - could you try with the following version of
rx-submatch? I don't have the slightest idea how this is supposed to
work :-(
martin
(defun rx-submatch (form)
"Parse and produce code from FORM, which is `(submatch ...)'."
(rx-check form)
(concat "\\("
(if (and (listp (cdr form)) (listp (cadr form)))
(mapconcat #'rx-form (cdr form) nil)
(rx-group-if
(mapconcat (lambda (x) (rx-form x ':)) (cdr form) nil)
(and (memq rx-parent '(* t)) rx-parent)))
"\\)"))
