How can I disable font-lock-mode in Emacs (actually XEmacs)? It appears that, upon seeing the first line of a Perl script: #!/usr/bin/perl Emacs sets font-lock-mode. But I do not wish to use font-lock mode when working with Perl scripts. I am editing a number of short Perl scripts, and I do not wish to go through the routine: M-x font-lock-mode to toggle off font-lock-mode each time I load a script for editing.
