Subject: [PATCH 5/6] howto: Tweak carriagereturn symbol at fvextra's auto line break

Also use "darkgray" as the color of symbols indicating the line break
to make it obvious that they don't belong to the command line.

Mention the option "-jN" of "make" in comments as well to tell readers
that parallel build is possible.
