get the first N unquoted lines of the article

[Ted Zlatanov <tzz@lifelogs.com>]

How would I get the first N unquoted lines of an article?  I couldn't
figure it out easily because of the many regular expressions involved in
each citing package.  I looked at gnus-cite.el but
gnus-cite-prefix-alist was not helpful, and gnus-dissect-cited-text
only works on the current article.  I tested with:

(defun gnus-extract-uncited-text-in-buffer (&optional buffer)
  (interactive "bBuffer to extract: \n")
  (let* ((gnus-article-buffer (or buffer gnus-article-buffer))
	 (sites (gnus-dissect-cited-text)) ; get it? sites, cites...  arghhhh
	 (text "")
	 (from (point-min)))
    (dolist (site sites)
      (let ((to (car-safe site))
	    (quote (cdr-safe site)))
	(when (string= quote "")
	  (debug to quote (buffer-substring from to)))
	(setq from to)))))

but it did not recognize the quoted regions separately.  Maybe it needs
the actual Gnus article buffer with its special setup?  In that case
it's not useful to me, because I need to extract those lines from any
text.
