Hey @ChristianRiesen sorry for the delay in response and thank you for your ping on Twitter. Had a chat with @simensen earlier today about permalinks and his main worry was that this would mess with permalinks in some way causing issues with services that require those like Disqus. The tests you've added should cover that 👍 . I'll run some tests over the weekend and get back with any feedback/change requests/merge this PR depending on my findings. This is definitely something we want to clear any confusion with our users regarding this subject.

Could you also open a PR to our documentation to document this behavior: https://github.com/sculpin/sculpin.io/tree/master/source/documentation

@ChristianRiesen looks good, I'll have a chat with @simensen again mainly because there is a part educating users and more maybe unforseen issues I have to look into.

In my case I change my perma link from :year/:month/:filename/ to :year/:month/:filename to get the same affect as without your PR. But for some reason my disqus URL still has a trailing /.
