[gnugo-devel] Leftd game and minor tuning

[bump]

This slight generalization of one pattern fixes an error
in leftd-gnugo-3.3.12-200211290140.sgf. After move 102
GNU thinks the B group in the lower rigth is alive
because a half eye is hallucinated around O5.

The game leftd-gnugo-3.3.12-200211290140.sgf is well worth
looking at. GNU plays badly until move 156, when W must have
thought he had a won game. After that B plays extremely well
for a spectacular win.

Moves 26, 120 and 126, among others, are serious errors that 
need looking at. The last two especially look like bugs.
