   * FILE_MONITOR_EVENT_RENAMED is equivalent to a delete/create
   * pair.  This is exactly how the events will be reported in the case
   * that the FILE_MONITOR_WATCH_RENAMES flag is not in use.
   * 
   * If using the deprecated flag FILE_MONITOR_SEND_MOVED flag and @a event_type is
   * FILE_MONITOR_EVENT_MOVED, @a file will be set to a File containing the
   * old path, and @a other_file will be set to a File containing the new path.

   * In all the other cases, @a other_file will be set to #<tt>0</tt>.
