There should be no problem in simple nakade cases. This patch will ignore 
self-atari liberties automatically, so in the case of 3, 4  and star 5 inner 
liberties, the patch will not generalize moves to other liberties then the 
crucial point. For other 5 and 6 liberties, I'm not sure gnugo can handle 
these complicated cases at this moment, i.e. semeai with opponent having a 
big eye. If yes, the patch can be upgraded simply.
