The More link in the block only uses clean urls

I was testing out the Monthly Archive and noticed that the 'More' link in the Monthly Archive block is created using only clean urls instead of testing if the site it using clean urls. So on drupal sites that aren't using clean urls it won't work. It's producing a link like http://www.example.com/month instead of http://www.example.com/?q=month.

I'm using Drupal 5.1 on a XAMPP 1.6a installation on Windows 2000. I haven't tried the module on my server yet, just the test site on my computer. (I like to make sure I'm not going to have problems with a module before throwing it on a live site.)
