Subject: 23.0.90; syntax-highlighting in shell-script-mode incorrect
Date: Thu, 19 Feb 2009 11:42:28 +0100

Syntax highlighting in shell-script-mode is incorrect if you put '
characters (single quotes) into double quotes without "escaping" them.
But this is only handled by the syntax highlighter as escaping, since
a single quote does not need any escaping in double quotes (this test
was only done to confirm that this is the actual issue that caused the
incorrect highlighting).

I cannot reproduce this.  Can you give us a concrete test case starting
from "Emacs -Q"?
