bug#6710: perl coloring not correct in emacs-22.3

[Warren L Dodge]

With this script named test.pl
#############################################################################
@temp = split/\./, $osNum;
$osNum = $temp[0];
#############################################################################
emacs-22.3 -Q test.pl

The perl-mode coloring is not correct. The regex changes color but it
doesn't terminate and the rest of the script is that same color.

If you put 

@temp = split(/\./, $osNum) ;

it works properly.

Whilst I see this in 22.3, it is fixed in 23.1 and up, so I suggest
upgrading.
