bug#997: perl mode blows "'" etc.

[jidanni]

Perl mode screws up bad with this file. Cperl mode gets it better.
$ perl -c p.pl
p.pl syntax OK
$ cat p.pl
/this is a perl program to demonstrate emacs's wacky color biz/;
/this line is in the wrong color until here'/; #///
/\b.*\bpic(ture)?s\b/;
/this line is in the wrong color/;
#this comment turns back on emacs correct color: \b\b
/this line is in the right color/;
/but not this line until the end\/;/m;
$ emacs -Q p.pl
Anyway, one usually ends up having to stick in special comments with
some / ; ` ' etc. in them lest large tracts of code become the wrong
color. emacs-version "22.2.1"
