[Bug-gnubg] More editing weirdness

[Timothy Y. Chow]

This may be just another manifestation of the same bug that I reported 
recently, but just in case...

As before, start up the graphical version of GNU on a Windows machine.

Enter edit mode, and paste in the following ID:

XGID=--BB-BB---a-BAAAA------bdA:1:1:1:61:0:0:1:0:10

Click on the little White checker icon beneath the board to set White on 
roll (White is the player on the far side of the board).

Ctrl-drag the Black checker on the bar to White's 6pt.

A sixteenth (!) White checker should miraculously materialize on the bar.
