   * What is the nicest behavior for import, from the user's point of
   * view?  This is a subtle question.  Seemingly intuitive answers
   * can lead to weird situations, such never being able to create
   * non-directories in the top-level of the repository.
   *
   * If 'source' is a file then the basename of 'url' is used as the
   * filename in the repository.  If 'source' is a directory then the
   * import happens directly in the repository target dir, creating
   * however many new entries are necessary.  If some part of 'url'
   * does not exist in the repository then parent directories are created
   * as necessary.
   *
   * In the case where no 'source' is given '.' (the current directory)
   * is implied.
   *
   * ### kff todo: review above behaviors.
