This patch brings more consistency in the presentation of comments, including: - 2 line spaces between blocks (M4 macro tend to make the file look quite bulky, so it is making the file more aerated) - fixes in the length of underlining - adding a few comments on the reason of the check to ease maintainance Signed-off-by: Christophe CURIS <christophe.curis@free.fr>
