Comment Syntax Highlighting in 22.1

[Mike Richards]

I decided to try out 22.1 today and noticed that comments are no
longer highlighted as in the 21.x series (this is at the console, not
xemacs).

For example, consider the following short file called 'test.pl':

#!/bin/perl -w
# this is a comment

In the previous version of emacs, the entire second line would be
highlighted red. But in 22.1 version only the pound sign is red, and
the rest of the line is in the default color (white).

How is it possible to get the entire line to be red again?
