    Bug 770123 - Add emacs locale settings for GNU coding style.
    
    Taken from: https://gcc.gnu.org/wiki/FormattingCodeForGCC
    I assumed it is upstream enough, but since I don't use emacs, I have not
    tested and just hope it is good. Do not hesitate to commit better emacs
    settings to follow our coding style!
