Private pure virtual methods.

I think I just hadn't considered that case. The next snapshot should be fixed.

I'd also question why you are using the Abstract annotation. It's only needed 
if you are skipping a pure virtual in the .sip file - don't use it if you are 
fully specifying the class. I've changed the documentation to try and make 
this clearer.
