23.0.50; latest change to blackbox.el breaks the game

[Sven Joachim]

The following change in revision 1.26 of blackbox.el causes breakage:

,----
| 2007-10-21  Dan Nicolaescu  <address@hidden>
| 
|       * play/blackbox.el (bb-up, bb-down): Use forward-line.
`----

After this change, bb-up and bb-down move to the beginning of the line,
no matter where point was before.  That renders blackbox pretty much
unplayable. :-(
