Drop-in replacement for vanilla perl-mode.el for Emacs 24.

This file was copied verbatim from the perl-mode.el packaged with my
version of Emacs (24.3 packaged for Ubuntu 13.10).  It is meant to be
loaded instead of the regular perl-mode.el.

Example, with this file saved as /home/fgabolde/.emacs.d/site-lisp/perl-mode.el:

(add-to-list 'load-path "/home/fgabolde/.emacs.d/site-lisp")

early in the init file should be enough to guarantee that it will be loaded instead of the globally-installed perl-mode.el.
