Bug#807444: stormbaancoureur: doc mentions non-shipped example keybinding file

[ydirson at free.fr]

Package: stormbaancoureur
Version: 2.1.6-1.1

Quoting README:

>For keyboard controls, you can customize the key mapping by copying the file
>.stormbaancoureur.keys.example to $HOME/.stormbaancoureur.keys and then editting
>it.

Having this file in the package would be a must!
