you're munging ampersands in HTML script

Ampersands are munged when added to Description HTML

You convert ampersands to & when added to HTML in the header description.
I have to use javascript to un-mung it:
var amp="&"[0];

and then build my string with it, e.g.
var uri = "http://example.com/?stuff" + amp + "another-argument";

If I write:
var uri="http://example.com/?stuff&another-argument";
you save the script as:
var uri="http://example.com/?stuff&another-argument";

PLEASE STOP!
