Tidy fails if html contains a section <![endif]—> #487
Description
Hello. First of all thank you for great work.
I found a little bug almost identical to this old one #153, but looks like here problem is with em dash.
I've constructed a little example
<html>
<title> Some title </title>
<!—[if mso]>
<![end if]—>
<body>
<p> Yada yada yada </p>
</body>
</html>
In this case all content in body will be cut off.
