[mod_python] Handler return value is rendered in output

Hi David,

It looks like you are using the publisher handler. It works at a higher 
level than a simple mod_python hanlder and looks after the apache return 
value for you. Anything returned by the published method will be sent to 
the client. For example

def comment(req):
     return 'Hello world'

would return "Hello world" to the browser. This is why you are seeing 
the extra 0 appended to your output.
