Python-mode fails on emacs 22
The ":safe" keyword to defcustom was added in emacs 23, and causes the defcustom that comes with emacs 22 to choke when python-mode is loaded.
Is there any workaround for this, other than upgrading to, and working through all the issues with, emacs 23?
Is the :safe keyword really necessary? What dire things might happen if I were to chop out all references to it in python-mode.el?
