Not a bug. It's documented in the formatting help (http://news.ycombinator.com/formatdoc http://news.ycombinator.com/formatdoc) Also documented in the FAQ: How do I make a link in a question? You can't. (This is to prevent people from using this method as a way of submitting a link, but with their comments in a privileged position at the top of the page. If you want to submit a link with comments, just submit it, then add a regular comment.)
