    dir-locals.el: Adds White Space support · 5923088d
    Andres Gomez authored
    Trailing white spaces will be now always highlighted, not just in
    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
     - 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
