bug#17980: perl-mode here document colors

[積丹尼 Dan Jacobson]

All I know is for me doing
# set file.pl
# su - nobody -c 'HOME=/tmp emacs '$@ & #for virgin environment
print "jjjjjj"; BLACK, PURPLE
print <<\EOF;   BLACK
</body>         BLACK, SHOULD BE PURPLE
</html>         BLACK, SHOULD BE PURPLE
EOF             BLACK

Now instead checking shell-script-mode, things look good except the
final EOF should be the same color as the initial EOF, not instead the
color of the body!

I am using Debian emacs24:
