What I mean is exactly this:

--8<---------------cut here---------------start------------->8---
(if (featurep 'xemacs)
    (defconst reftex-label-regexps '("\\\\label{\\([^}]*\\)}"))
  (defcustom reftex-label-regexps
    '(;; Normal \\label{foo} labels
      ;; keyvals [..., label = {foo}, ...] forms used by ctable,
      ;; listings, minted, ...
    "List of regexps matching \\label definitions.
The default value matches usual \\label{...} definitions and
keyval style [..., label = {...}, ...] label definitions.  It is
assumed that the regexp group 1 matches the label text, so you
have to define it using \\(?1:...\\) when adding new regexps.

When changed from Lisp, make sure to call
`reftex-compile-variables' afterwards to make the change
    :version "24.4"
    :set (lambda (symbol value)
           (set symbol value)
           (when (fboundp 'reftex-compile-variables)
    :group 'reftex-defining-label-environments
    :type '(repeat (regexp :tag "Regular Expression"))))
--8<---------------cut here---------------end--------------->8---

I've already committed the above to the emacs-24 branch which is synced
also to master regularly.

I'm closing this bug.
