Out of curiosity, why do you receieve wishes for GNU Go?  Do you
maintain a GNU Go package?

This simple patch makes the last move always visible, unless it happens
to be a pass move, and also prints it to the right of the board.  I didn't
try to implement move history.

However, I suggest that you use some client with GNU Go as ASCII mode is
very old, inconvenient and almost not supported.  Try googling for
something like ``GTP client GNU Go'', maybe also specifying your OS.
