    dir-locals.el: Adds White Space support · 16fabfb3
    Andres Gomez authored
    The White Space package, which is available since GNU Emacs 22, is
    loaded and activated locally in prog-mode and cmake-mode.
    
    Also, using White Space variables, we set highlighting through faces
    on wrong indentation and the maximum length of a coding line.
    
    Notice that:
     - The highlighting for the characters beyond the set length of a
       coding line is not activated by default, only for wrong
       indentations.
     - If the White Space package is not available, errors on loading or
       activation are ignored.
     - If the White Space mode is not activated the set variables would
       not have any effect.
    
    v2: python-mode inherits from prog-mode
    v3: Removed too long lines trail highlighting, as suggested by Ilia
        Mirkin.
