Re: require-final-newline

[Carsten Dominik <carsten.dominik@gmail.com>]

To be honest, I am not sure that this is the right solution.  For some 
operations in org-mode, like structure editing, that final newline is 
good to have.  Also, this issue with the final newline is depending on 
personal preferences.

I tend to believe that the better solution is to fix outlining, so that 
it will never hide empty lines at the end of the buffer.  Hope you can 
agree if I implement that latter solution.
