bug#12373: 24.1; cperl-mode syntax highlighting

[Stefan Gottschalk <SGottschalk@nvidia.com>]

Hi, Stefan.  

Thanks for looking at this.
I tried your repro - and it works fine for me too.

My apologies!  
I will work up a better repro - or be happy that I can't make it happen!

Hmm... handling of $' in Perl is tricky, so I wouldn't be surprised if it still has bugs, but when I try a Perl file (using cperl-mode) with just the above line in it, it is displayed correctly both by Emacs-23 and Emacs-24.  Here's the command I used to test:

 % emacs24 -Q --eval "(defalias 'cperl-mode 'perl-mode)" test/indent/perl.perl

And here's the perl.perl file:

   #!/usr/bin/perl

   $fileType_filesButNot           # bug#12373
       = join( '|', map { quotemeta($_).'$' } @{$fileType->{filesButNot}} );

Using `perl-mode' instead of `cperl-mode' also seems to work fine.
Can you send us another test case that exhibits the problem?
