[web2py] lot's of X's in error responses

[howesc]

in http.py there exists this block:

            if isinstance(body, str):
                if len(body) < 512 and \
                        headers['Content-Type'].startswith('text/html'):
                    body += '<!-- %s //-->' % ('x' * 512)  # trick IE


when i'm using request.restful i don't necessarily want all of those 
X's......would it be ok for me to make a patch that skips this block in a 
restful request?  (is this IE hack still relevant?)

thanks!
