all-redirects needlessly escapes special characters in URIs for XML

[Johannes Rössel]

When using the API with all-redirects=1 the redirects have & escaped to &amp; in the XML output (which isn't necessary since they are enclosed in <![CDATA[...]]>

Example:

   http://api.longurl.org/v2/expand?all-redirects=1&url=http://is.gd/hCXd46

yields:

<?xml version="1.0"?>
<response>
    <long-url><![CDATA[http://www.google.com/?foo=bar&boo=far]]></long-url>
<all-redirects>
<redirect><![CDATA[http://google.com/?foo=bar&amp;boo=far]]></redirect>
<redirect><![CDATA[http://www.google.com/?foo=bar&amp;boo=far]]></redirect>
</all-redirects>
</response>
