[Bug-gnubg] Joining or including .sgf games

[Albert Silver]

Hi,

        I have a problem. I'm in the process of preparing a very long
and detailed analysis of a match file. There are many rollouts in it,
but I've encountered a mistake in the 18th game's notation. I know how
to start a game over or continue from a certain point, so I can easily
overwrite the last moves of the game, but doing so will erase the
subsequent 11 games as well. How can I re-attach the following 11 games
to the main file without losing the information accumulated in the first
18 games? I'd like to preserve the statistics of the entire match,
otherwise I'd just split them in two files.

                                                Albert
