Yes, that would be nice, so I've now implemented it.  However, there's
one false positive:

(defcustom erc-button-alist
  '(('nicknames 0 erc-button-buttonize-nicks erc-nick-popup 0)

[...]

                (choice :tag "Matches"
                        regexp
                        (variable :tag "Variable containing regexp")
                        ;; FIXME It really does mean 'nicknames
                        ;; rather than just nicknames.
                        (const :tag "Nicknames" 'nicknames))

And this really means 'nicknames.  Anybody got any suggestions how to
work around that?
