That's a regular expression my friend, the way emacs identifies file
types (in this case).  Read the friendly manual on Emacs/POSIX regular
expression syntax under "M-x info" (this takes you into info mode,
then you can read the Emacs manual, a chapter of which is dedicated to
regular expressions).

As annoying as the message is, you can enable font-lock by typing "M-x
font-lock-mode RET" or putting 

;; Global font-lock mode
(global-font-lock-mode 1)
into your .emacs file.  This enables font lock by default for every
buffer.  I love it.  Every buffer comes up all colorful...

By your newbie warning, do you mean you're new to Emacs, or new to
Emacs 22?
