Readline treats SIGTERM as a fatal signal, like SIGHUP. This allows it to
exit the calling application if, for instance, the terminal emulator
window in which it's running is closed.
Well, SIGTERM has nothing to do with tty's closure, why does it
do that *on SIGTERM*?
Because terminal emulators send SIGTERM to the foreground process group
when you use the `close' button instead of exiting the running application.
