[Stefan Monnier]

branch: externals/gnugo
commit a4b96a14380aa07d10a4d6abbc63f41cadd9d78a

    [gnugo int] Use ‘number-sequence’ more.
    
    * packages/gnugo/gnugo.el (gnugo-animate-group):
    For image display ‘spec’ handling, don't map over
    an exploded string, ignoring the individual characters,
    and manually toggling the state; instead, map over an
    integer, using the number's divisibility by two to select.
