   *

   * Expected behaviors:

   *  - Adding a new revision will make another entry in the field table, but

   *    the original file will not be duplicated.

   *  - Deleting a revision should not delete the original file if the file

   *    is in use by another revision.

   *  - When the last revision that uses a file is deleted, the original file

   *    should be deleted also.
