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.
