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)

See Scrolling conservatively in The GNU Emacs Manual, for details.
