Re: Doc: NR 4.4.1: Rewrite. (issue2642043)

[markpolesky]

Here's the next patch set for the
"Vertical spacing inside a system" doc stuff.  I
tried to address everything you guys mentioned; let me know
what you think.  One significant thing I did here was
to remove the entire @subsection called
"Vertical spacing between systems", since I don't think it
was really doing anything.

I guess I'm ready for the next round of reviews.
Thanks.
