This has always been Scid's behavior, a matter of discussion. If I'm right,
Scid's internals does not allow to append var at the the end of the game,
and the solution is to enter a comment "game could have continue with..."
and enter the next moves as a main line.
Or, just go back one move, reenter same move as var, etc.

This is what is done when annotating a game, and to show how the game could
have continued.

This would mean adding an extra button for "add all multi-pv lines", which
is better than changing lines number.
Volunteers ?

Yes, but some people liked to see the history of engine's thinking. So with
an xboard engine, you get history, with an UCI engine you get N best lines.
I also don't think it is useful to see history of engine's thinking, but now
I only use UCI engines, so I don't really care.
