I often have some html in an untitled buffer. It would be nice if InfoViewer would display that html as html rather than plain text. Currently, the file must be saved with an html extension for InfoViewer to render the buffer text as html.
The attached patch sets the content type to "text/html" if the buffer mode is html, which solves this issue.
