[elpa] externals/gnugo bcc7fef 166/357: [gnugo maint] Update HACKING; nfc.

[Stefan Monnier]

branch: externals/gnugo
commit bcc7fefc53c4ab030c37f17297128b03ebef2725
Author: Thien-Thi Nguyen <ttn@gnu.org>

    [gnugo maint] Update HACKING; nfc.
    
    The debugging aids functionality is now part of gnugo.el.
    
    The various ideas / wishlist items are now realized, except for
    "dribble the SGF tree", which is bunk, and "SGF tree traversal",
    which awaits a nicer (user-level) node-ref facility.

     Hmm, lots of symbol trickery going on; initial attempts FAIL.
