    main: Print \n upon EOF (CTRL-D) when run interactively

    Exiting dash via a ^D instead of with "exit" causes dash to forget to
    print a newline.

        sh-3.1$ sh
        sh-3.1$ ^D
        sh-3.1$ dash
        $ sh-3.1$

    It is more neat and tidy to send a newline similarly to what bash does,
    so it doesn't make the next prompt of the parent shell look ugly.

    Suggested by jidanni.
