Ok, I've not been entirely correct here: when an engraver has an
acknowledger or end_acknowledger listening on line-spanner-interface,
adding the interface to OttavaBracket will cause OttavaBracket to start
triggering the respective acknowledgers.

In this case, however, I don't see any engravers acknowledging
line-spanner-interface.  So indeed at the current point of time, adding
line-spanner-interface to OttavaBracket should not make any difference.
