Proudly presenting excellent test coverage for HAML.

C0 is at 99.0%... all except for one experimental feature.

So, now any changes have something to be tested against which should be a fairly strong background.

Now, the only problem left is that whitespace active areas get fucked. That's not a good thing. Once we get a 
philosophical stance on such subjects, then we shall figure crap out about what that all means.
