commit fd1fb6d2f588e9f7da7567bb00a42a8e28134ea5
Author: Thien-Thi Nguyen <t...@gnu.org>

[gnugo] Fix bug: Compute grid spacing using offset math.
OBOE introduced 2006-04-09 (release 2.2.13).
* packages/gnugo/gnugo.el (gnugo-refresh):
Don't use ‘wmul’ directly to compute ‘gspc’;
instead, use one plus the re-derived image pixel-width.
