Tidy choking on quotes-within-quotes in javascript

The following javascript gets it's quotes mangled (escaped) by Tidy:

document.write("<img src='http://domain.com" + document.referrer + "' 
width=1 height=1>");

Become:

document.write("<img src=\'http://domain.com" + document.referrer + "\' 
width=1 height=1>");

How can I prevent this? I couldn't find an appropriate Tidy directive.

Thansk!

PS please reply both to me and the list as I am new to this ML and for 
some reason I am not receiving posts ...
