Re: feature proposal: change-log-exit: save change-log buffer and bury it.

Sorry for the delay in my answer. My memory did not serve me well. I
thought this was in Emacs 19.34 but I could not find any working Emacs
19.34 version anymore. However it is a Xemacs function.


(defun change-log-exit ()
  "Save the change-log buffer, and restores the old window configuration.
Buries the buffer."
  (interactive)
  (save-buffer)
  (let ((buf (current-buffer)))
    (pop-window-configuration)
    (bury-buffer buf)))

The problem is bury-buffer, it is a C function from buffer.c that of
course makes it more difficult to port to GNU Emacs.

The definition of 
 pop-window-configuration

You find below.


So the short question is: can such a functionality implemented easily I
found it very useful.

Right now I use

(defadvice change-log-find-file (before savebury activate)
  "Save and kill the buffer before turning to source."
  (save-buffer 1)
  (kill-this-buffer))



Thanks

Uwe
