Comment (by simonpj):

 It'd be great to fix this -- and document the invariant on
 `normaliseType`, namely that the result has the same kind as its argument.

 As I understand it, that's entirely consistent with our new (and now
 implemented in HEAD) story, that flattening does not change the kind of
 the type being flattened.

 Richard: are you up for doing this?  I assume that the "my branch" part is
 now water under the bridge, because the new flattening stuff is done.
