with-current-buffer

["Andreas Röhler" <andreas.roehler@easy-emacs.de>]

Hi,

docstring of "with-current-buffer" says:

"Execute the forms in BODY with BUFFER-OR-NAME temporarily current."

However, seems the old buffer isn't stored, buffer-or-name specified 
here remain current.

Also don't see inside the macro which way the old buffer should be restored:

(defmacro with-current-buffer (buffer-or-name &rest body)
   "Execute the forms in BODY with BUFFER-OR-NAME temporarily current.
BUFFER-OR-NAME must be a buffer or the name of an existing buffer.
The value returned is the value of the last form in BODY.  See
also `with-temp-buffer'."
   (declare (indent 1) (debug t))
   `(save-current-buffer
      (set-buffer ,buffer-or-name)
      ,@body))


A bug?

Thanks,

Andreas,
