--- Begin Message --- Subject: 23.1; can't escape quotes preceded by certain characters in perl-mode Date: Mon, 01 Aug 2011 09:58:10 -0500 User-agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:5.0) Gecko/20110624 Thunderbird/5.0 When I try to escape quotes with a backslash, within quotes, the coloring in perl-mode breaks in a very specific way. It depends entirely on the characters that precede the backslash. For example, this works fine:

$a = " x \"string\"";

but if you replace the 'x' with m, q, s, or y, then Emacs thinks you're still inside a quote.

You can find a screenshot here:

I've tried this in emacs 23.1, 23.2, and 22.2 on Windows and Linux and the problem is the same in all of these versions.

Thanks
