I inherited this .emacs file from someone else who had this
set. I'm guessing it used to be customizable? If it really isn't
proper to customize it this way thats fine. I can disable it with
no real issues. I can just change the regexps I am using in
font-lock-add-keywords. I assumed that it could be customized
because if I did a search the customize option for it showed up,
but maybe improperly setting it with custom-set-variables just
adds it to Customize.
