darcs patch: Add liftField and maybeField to ParseUti... (and 1 more)

[Bertram Felgenhauer]

Hi,

I'd really appreciate some feedback on this, did anybody look at it?

I believe the first patch could help Cabal even if installing packages
hidden will not become a (Distribution.Simple) Cabal feature.

regards,

Bertram
