rcirc: Scrolling conservatively

 
 4.3 Scrolling conservatively
 ============================
 
 IRC buffers are constantly growing.  If you want to see as much as
 possible at all times, you would want the prompt at the bottom of the
 window when possible.  The following snippet uses a local value for
 ‘scroll-conservatively’ to achieve this:
 
      (add-hook 'rcirc-mode-hook
                (lambda ()
                  (set (make-local-variable 'scroll-conservatively)
                       8192)))
 
    SeeScrolling conservatively (emacs)Scrolling, for details.
