    Correctly set require-final-newline
    
    Emacs provides `mode-require-final-newline` to allow users to control
    the behaviour of modes (like `dockerfile-mode`) which are designed to
    control the final newline in a file. The intent is that this is set to
    `t` by default - modes that wish to ensure a final newline should set
    `require-final-newline` to `mode-require-final-newline`, allowing users
    to override this behaviour. See
    
    http://www.gnu.org/software/emacs/manual/html_node/emacs/Customize-Save.html
    
    for more detail.
    
    One specific use case where this is important is `ethan-wpace`, which
    implements a more sophisticated whitespace policy. Some examples of how
    sidestepping this convention can be a problem can be found in issues
    glasserc/ethan-wspace#22 and glasserc/ethan-wspace#25.
