  Following code is available to MIME safe signature handling using
tm-view:

(defun gnus-narrow-to-signature ()
  "Narrow to the signature."
  (widen)
  (if (and (boundp 'mime::preview/content-list)
	   mime::preview/content-list)
      (let ((pcinfo (car (last mime::preview/content-list))))
	(narrow-to-region (mime::preview-content-info/point-min pcinfo)
			  (point-max))
	))
  (goto-char (point-max))
  (when (re-search-backward gnus-signature-separator nil t)
    (forward-line 1)
    (when (or (null gnus-signature-limit)
	      (and (numberp gnus-signature-limit)
