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
