Revert "Merge pull request #18 from michaelt/patch-1"

This reverts commit 9536c6cadf91bb6ef7dbdf3a2a85c7a7cd378e20, reversing
changes made to 8f0aa6e3ef62a1c53f69977e4e7246520ce10dd9.

The reason for this revert is that I had some commits locally which I
haven't pushed to github, yet there were on Hackage, so I'd like to push
those first. I'll revert this revert in a couple of commits from now.
