+Subject: [PATCH] Don't apply cramming damage to players
+
+It does not make a lot of sense to damage players if they get crammed,
+ especially as the usecase of teleporting lots of players to the same
+ location isn't too uncommon and killing all those players isn't
+ really what one would expect to happen.
+
+For those who really want it a config option is provided.
