[Stefan Monnier]

branch: externals/gnugo
commit f102d7f5cc18df40bec890377bd41df4657acc8c
Author: Thien-Thi Nguyen <ttn@gnu.org>
Commit: Thien-Thi Nguyen <ttn@gnu.org>

    [gnugo] Allow user to move for GNU Go.
    
    * packages/gnugo/gnugo.el (gnugo--user-play):
    Don't hardcode WHO to ‘gnugo-push-move’;
    instead, compute it from :last-mover.
