MFC r197956:

- Catch SIGHUP to perform cleanup before exiting.
- Exit if getch() returns with an error other than EINTR. Otherwise
  systat(1) may get stuck in an infinite loop if it doesn't receive
  SIGHUP when terminal closes.
- Remove attempt to clear stdio error indicators. getch() doesn't use
  stdio, making it useless.
- Remove unneeded masking of getch() return value.
