  * Adjust unlit's behaviour on continuing comments
  This behaviour is not set in stone, there is not full agreement yet.
  The previous code was deciding wether to continue a comment based on wether
  the intervenienting lines were completely blank or had at least one space in.
  The other suggestion was to use a '.' to continue a comment line.
  Instead, this change uses a single blank line between comments to continue
  a comment and anything else terminates it with a blank line.
