bug#1997: 23.0.60; write-region fails in pmail

[Richard M Stallman <rms@gnu.org>]

I use this function to write HTML code from certain messages:

(defun lynx ()
  (interactive)
  (unless (re-search-backward "^From wget@gnu.org" nil t)
    (goto-char (point-min)))
  (save-excursion
    (search-forward "/bin/sh")
    (forward-line 3)
    (let ((start (point)))
      (search-forward "!EOF!")
      (beginning-of-line)
      (write-region start (point) "~/foo.html"))))

Instead of writing from the view buffer as it used to,
it now writes from the mbox buffer.  It writes the WHOLE mbox.

I presume this is due to the changes to use an existing hook and its
warts, instead of a feature designed to be simple to use for this job.
I verified that pmail-write-region-annotate was called with arguments
369 87214.

Any attempt to write part of the view buffer into a file
has the same problem.
