[Bug-gnubg] Surprising behaviour in cubeless play

[Philippe Michel]

When choosing to play without doubling cube (in settings / options / 
cube), the following warning is displayed :

"Use of the doubling cube is disabled.
Note that you'll have to disable the Jacoby rule if you want gammons and
backgammons to be scored (see `help set jacoby')."

What could be the point of this behaviour ? Shouldn't the Jacoby rule 
always be ignored in cubeless play ?

The way this is documented suggests this is a choice, not an oversight. 
Does anyone who has been following gnubg's development for long enough 
remember why it is done this way ?
