bug#14085: 24.3.50; regression `C-c C-c' in `report-emacs-bug' no longer closes the report window

["Drew Adams" <drew.adams@oracle.com>]

Until recently, when you hit `C-c C-c' in the report buffer that buffer
was buried, and you were returned to the buffer that was shown when you
did `M-x report-emacs-bug'.  This is no longer the case.  (Well, the
buffer *sent...* is shown instead of *unsent...*, but it is the same
report.  The point is that the report remains visible, instead of the
buffer you were working in before creating the bug report.)
 
(I use a mail client - Outlook, if that makes any difference.)
 
Note, BTW, that there is no change in the default value of
`message-kill-buffer-on-exit' - it is still nil, as it was in Emacs 24.3.  And
the definition of `message-send-and-exit' (which is bound to `C-c C-c') has not
changed.  Something else has introduced this regression in behavior.

Ah, it seems that this is perhaps the culprit: a change to `message-bury'.

It used to do this:

(defun message-bury (buffer)
  "Bury this mail BUFFER."
  (if message-return-action
      (progn
        (bury-buffer buffer)
        (apply (car message-return-action) (cdr message-return-action)))
    (with-current-buffer buffer (bury-buffer))))

And now it does this:

(defun message-bury (buffer)
  "Bury this mail BUFFER."
  (bury-buffer buffer)
  (when message-return-action
    (apply (car message-return-action) (cdr message-return-action))))

In my case, at least, `message-return-action' is nil.  This means that the
`with-current-buffer buffer' is no longer used, so it seems like the wrong
buffer gets buried.
