viridian: remove comments referencing section number in the spec

viridian: remove comments referencing section number in the spec

Microsoft has a habit of re-numbering sections in the spec. so avoid
referring to section numbers in comments. Also remove the URL for the
spec. from the boilerplate... Again, Microsoft has a habit of changing
these too.

This patch also cleans up some > 80 character lines.

Purely cosmetic. No functional change.
