Oh, that makes sense.  xemacs doesn't need that, but emacs does.  Since 
John's init.el was for xemacs, he wouldn't have included it.  Maybe we
can get him to add that so it will work for both.  Something like:
; xemacs has font-locking on by default, but not emacs
(if (not (featurep 'xemacs)) (global-font-lock-mode 1))
