    I have never seen a blank line added. If there is no newline at
    the end of the file, one will be added. That is not a blank line.
    a blank line at the end would mean two newlines at the end of the
    file.

    A final newline is required by many UNIX utilities. The POSIX
    definition of a text file is one that ends with a newline.
