[BUG] html-encoding not always applied to "&" characters

The Petal docs say that, by default, ampersands (and some other
characters) are encoded to &amp;

I have a case where this doesn't always happen; if I create a URI
object like so:

    $document->{uri} = URI->new ("http://example.com/test.cgi?foo=test&bar=test");

..and use it in a template in two equivalent ways:

    <p tal:content="string: ${uri}">stuff to be replaced</p>
    <p tal:content="uri">stuff to be replaced</p>

..I get two different results (the second one is invalid XML):

    <p>http://example.com/test.cgi?foo=test&amp;bar=test</p>
    <p>http://example.com/test.cgi?foo=test&bar=test</p>
