Feature request: support for named links

So a lot of blogs have this cool thing where the blog post URL is like a word or two. Easy to remember, easy to share and really quite nifty. For example, posts on http://paulgraham.com/ have urls like http://paulgraham.com/genius.html or http://paulgraham.com/useful.html

Being able to do something like this if one chooses would be great, maybe through a 4th line option.
