Hackage provides updated .cabal package descriptions i.e., to update
dependency version ranges. Unfortunately haskell-build-system has this
extra quirk to fetch them. Since the importer does not update
cabal-revision when updating the version this was missed when I did the
last big Haskell update. Would be nice if we could merge multiple origins
in the source field.

Cheers,
Lars
