It might be nice to provide a "paranoid-quit" option which, like Mutt,
prompts for "are you sure, or did you just hit the wrong key?", and, if
on, bind that routine to all of 'q', SIGINT, and SIGQUIT.

(I keep wanting ^C to interrupt a long-running process within sup like a
!!, and being surprised when it quits and I'm reminded I need to ^G.
And q is way too dangerously easy to hit for someone who migrated over
from Mutt.  I'd definitely turn that on, at least for a few months until
the proper keybindings stick in my mind.)
