which-function-mode: only enable in emacs 24.4 and later Emacs 24.3.x has a bug in which-function-mode that causes my emacs to lock up for several seconds. Rather than tolerate that, just disable which-function-mode on those systems.

#!/bin/sh
if [ "`uname`" = "Darwin" ] ; then
    open -a emacs "$@"
else
    emacs -nw "$@"
