Subject: [PATCH] Prevent crashes if no ttyrec files can be associated with a
 game.

If the postprocessing step finds no ttyrec files created between a
game's end and the previous game's end, it will no longer index an
empty list and crash.

The condition of finding no ttyrec files is still a bug that requires
investigation.
