  * The Read instance for License and InstalledPackageInfo is authoritative
  It is ghc's optimised InstalledPackageInfo parser that needs updating.

    * Fix Show/Read for License
    We were ending up with things like
        InstalledPackageInfo {
            ...
            license = LGPL Nothing,
            ...
        }
    i.e. "LGPL Nothing" rather than "LGPL", which we couldn't then read.
