Fix for Program hack in bsdgames-2.17.25 core dumps when you enter 'i' after restoring a saved game

[Richard Henschel]

The following patch fixes the problem. Cut and paste may have converted tabs to spaces (sorry).
I sent this to lists.debian.org as well, but not sure if that is the right place.
I am running Ubuntu 17.10 and package lists as bsdgames-2.17-25, but this fix was done in source listed as bsdgames-2,17-26build1, so that version is also broken.
