HTMLParser fix

I ran into a problem this evening getting the HTMLParser to parse an
html page with embedded script tags which contain end tag elements
inside the script.  Take the following html for instance:

<html>
<body>
<script>
<!--
document.write('<h1>testing</h1>');
-->
</script>
</body>
</html>


In the HTMLParser module which comes with Python 2.2.1chops this up
and returns the </h1> as a tag event when it should be part of a data
event.

The following patch should fix this problem:

<         self.handle_data(''.join(self.cdata))
<         self.cdata_mode = 0
<         self.cdata = []

<                     self.cdata.append(rawdata[i:j])
<                 else:
<                     self.handle_data(rawdata[i:j])

<                 self.clear_cdata_mode()
<             else:
<                 self.cdata.append(rawdata[i:j])
<                 return j
