Behold this is a problem: if it is runned within a branch&tree, it deletes
the workingtree!
I assume this it because of the values in reconfigure.Reconfigure:
    def set_repository_trees(klass, bzrdir, with_trees):
        """Convert a repository branch into a standalone branch"""
        reconfiguration = klass(bzrdir, with_trees=with_trees)
        reconfiguration._plan_changes(*want_tree=False, want_branch=False,
                                      want_bound=False,
want_reference=False,*
                                      want_shared_repository=True)

this is dangerous IMHO.
I think you should only allow running this directly in a repo (or when a
repo location is specified exactly).
