I made this, but - just like everything else that they've touched in the last year - GitHub has completely ruined the GIST portion of the site. When you go to gist, you don't get automatically logged in. Then you post something which is now owned by "anonymous", and there's a "sign in to comment button" which automatically logs me in. That's some horrible UX. Why did they get rid of the "Login to claim this gist" button? Oh well.

Now I have to fork it if changes ever occur. Fantastic.
