    dir-locals.el: Adds White Space support · 5923088d
    Andres Gomez authored
    Trailing white spaces will be now always highlighted, not just in
    prog-mode.
    
    Also, the White Space package, which is available since GNU Emacs 22,
    is loaded and activated locally in prog-mode.
    
    Additionally, 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: Removed too long lines trail highlighting, as suggested by Ilia
        Mirkin.
