ToME crash on angband.live

[HugoVirtuoso]

I said to others at angband.live about a potential serious bug affecting specifically that ToME version on that webserver: If you use 'ctrl-c' (lowercase) it insta-closes the game without saving and without warning. Just not too long ago, I lost a clvl 35 character due to this.

I haven't tested if offline installations are affected at all. I also don't know if ToME 2.4.0-ah is affected either. The one on angband.live is version 2.3.11-ah.
