The illusion is complete!

Ctrl-C is the traditional unix forced-exit mechanism, but perhaps we
could emulate mutt and have it prompt you before quitting. (And in
contrast to regular quit, it shouldn't save state back to the index.)

bin/sup already wraps everything in a rescue Exception, so you just need
to check within the rescue block whether it's a ctrl-c exception or not.
Something like:

  rescue Exception => e
    exit 1 if e.is_a?(Interrupt) && BufferManager.ask_yes_or_no("Die now?")
  end
