Bugfixes
I fixed a couple of bugs in the comment system tonight. First, there was a problem where an incorrect answer to the spam question would erase the fields entered into the comment form, which was inconvenient to a would-be commenter who I am sure accidentally typed the wrong answer.
The cookie that keeps track of the fact that you answered the question was set to only be valid for the current archive directory, so it only worked for posts made in the current month. It is now valid for the entire blog.
I also fixed an issue with the display of commenters' names who decline to leave a URL. The names now display in plain text instead of as a link to the current page.
