Because IE browsers, when they receive a error page (HTTP x!=200) and the
content is less than a certain size, they choose to ignore the content and
display an uninformative canned message instead. web2py injects in the
content an html comment to make it just long enough so that IE browser do
not ignore the comment. This is important for example so that IE displays
web2py tickets instead of a generic error page.
