Font-lock keywords broken in cfengine-mode

Font-lock keywords broken in cfengine-mode

[Romain Francoise]

Entering cfengine-mode makes the following appear in the Messages
buffer:

  Error during redisplay: (wrong-type-argument listp \)

The problem goes away after reverting this change:

2006-09-11  Stefan Monnier  <monnier@iro.umontreal.ca>

	* progmodes/cfengine.el (cfengine-font-lock-syntactic-keywords): Newvar.
	(cfengine-mode): Use it.  Fix \ syntax to be like /.

(This is Debian bug #404244.)

This does not happen when I try it.  It must depend on some other
details.  (I am using a tty, for instance.)  Can you present a
self-contained test case, and figure out what else we need
to know to make this fail?

The buffer must be non-empty (otherwise font-lock doesn't kick in).

The following steps should suffice:

 1. echo '# -*- cfengine -*-' >/tmp/cf.test
 2. emacs -Q /tmp/cf.test
 3. C-h e

Does this fix it?
