Yah! I was a bit surprised myself when I discovered that the browsers
would sniff to such an extent and that each browser was implementing
this differently. This will be a good addition to WebKit.

QtWebKit doesn't have any content sniffing and so Arora also has its
own crude ContentType handling.

I only speak for myself and not QtWebKit, but I think this is a good
move for something that can be moved into WebKit.

For what it is worth with Konq with its KParts system will follow the
content type and just load a a text editor in the browser if there is
no content-type for example.
