Bug#845269: patch to make backspace to 'undo' last move

[Bill Allombert]

Package: brutalchess
Version: 0.5.2+dfsg-7
Severity: wishlist
Tags: patch

Dear Debian Games team,

I did not find a way to undo the last move, so I made this simple patch
that causes backspace to undo the last move. This makes this program
much more enjoyable.

Cheers,
