commit 29fe160616b52c4a65b5d6056a6eff36bfb01561

    package.delete() also deletes empty packages
    
    Once a Package object no longer contains any files (archives or hints),
    it can be removed from the package set.
    
    (This fixes calm complaining when it wants to vault a stale package
    which had source, but no kept version does. Otherwise it complains that
    the source package has no versions)
