 So, you can either get rid of GNU emacs, or change it to use saner

+This will define the M-x linux-c-mode command.  When hacking on a

+to your .emacs file if you want to have linux-c-mode switched on

 But even if you fail in getting emacs to do sane formatting, not
 everything is lost: use "indent".
