- Toggle MARK_ISSET() at the beginning of the function instead
of setting it in one place and unsetting it in another place.

do_suspend()
- Use handle_hupterm() to handle SIGHUP and SIGTERM so we can
properly deal with them while nano is suspended. (DLR; problem
found by David Benbennick)
abcd()
- Removed, as it's unneeded due to the low-level input overhaul.
