patch applied (cabal-branches/cabal-1.4): Add PackageIndex.reverseDependencyClosure

Tue May 6 16:49:02 PDT 2008 Duncan Coutts * Add PackageIndex.reverseDependencyClosure It's similar to dependencyClosure but looks at reverse dependencies. For example it's useful to find all packages that depend on broken packages and are thus themselves broken.
