PR misc/49132 follow up

["J. Lewis Muir" <jlmuir%imca-cat.org@localhost>]

Hello!

I just wanted to follow up on PR misc/49132 that I submitted in August
to improve the "Obtaining the sources" chapter of the NetBSD Guide.  The
PR includes a patch to clarify and document the security/critical branch
in this chapter.  Is there anything I can do to improve the PR or help
it along?

Thank you!

Lewis
