ghc-pkg query feature request

Hi! When working with multiple versions of a package you often want to use the most recent version. A feature that would help for package systems is to be able to query ghc-pkg for the best version, or to list the versions in increasing version order. Something like: $ ghc-pkg best_version Cabal Cabal-1.1.1 $ ghc-pkg versions Cabal Cabal-1.0 Cabal-1.1.1 You get the picture. Obviously, this feature isn't critical since we could use 'ghc-pkg list' and work our way from there, but it would be nice. If you like the idea we might send you a patch. What do you think?
