Re: message buffer

[Rodrigo Amestica <ramestica@nrao.edu>]

Hi Ron,

many thanks for this code. It did not work right away on emacs 23.1, I
needed the following change in zoom-message (just at the beginning of
the function):

    (let ((pop-up-windows nil)
          (p (selected-frame))
          (b (buffer-name))
          (f (make-frame)))
      (select-frame f)
      (pop-to-buffer b)

setting pop-up-windows to nil avoids the horizontal splitting of the
window in the new frame.

many thanks,
 Rodrigo
