commit 0d16d35b138e3f57f30db38d225ce99355141f09
Author: Simon McVittie <smcv at debian.org>

    Only remove the alternative for /usr/games/wolf4sdl if it exists
    
    This fixes the following sequence: install wolf4sdl in jessie,
    remove (but do not purge) wolf4sdl, upgrade from jessie to stretch,
    and install wolf4sdl again. (Closes: #856722)
