Three patches for cabal

[Simon Peyton-Jones]

I'd be quite happy to rename the flag to GeneralisedisedListComp, and clarify the user manual.  Would that suit everyone?

I suppose the alternative is to leave it as TransformListComp, and document that fact.  But I rather agree that GeneralisedListComp fits the literature better.
