Thanks to have taken the time to try my patch.
As you can see it only add a keystroke for a feature that was already
in the original code (unlimited undo).

I agree the behavior is a bit odd (you have to press backspace 3 times
to undo a move) but I am used to it so "it works for me" :)
The only serious bug is if you try to undo the first move, then it
freezes.

I will look whether I can improve it.
