[Bug-gnubg] Bug in GamesGrid .txt output

[David Montgomery]

Hi gnubg developers,

There is a bug in GamesGrid's .txt output.  At least in
some circumstances when a move is forced, the most is
not written to the .txt file.  Here is an example,

 Game 2
 MarcGray,1627 : 0                dlevy,1857 : 1
  1)                             36: 24/18 13/10
  2) 36: 24/18 18/15             63: 25/22 24/18
  3) 13: 8/5 6/5                 46: 8/2 6/2
  4) 64: 15/9 13/9               12: 13/11 11/10
  5) 52: 24/22 13/8              56: 10/4 13/8
  6) 54: 8/3 13/9                33: 25/22 6/3 6/3 13/10
  7) 64:                         35: 25/22 13/8
 
7) 64: should have have 25/21*.

This is on our bug list, but I don't know when we're
going to fix it.  I'm letting you all know in case
someone would like to patch gnubg to successfully
import these.  Snowie doesn't complain about them.

In the meantime, GamesGrid's .sgg format is probably
a better choice.  It handles NackGammon better and
records automatic doubles, among other things.  

(Another project is for me to review the extensions
to .txt that gnubg has added to support things like
autos, Nack, raccoons, droppable beavers, etc.)
