The extracted bmake tarball from last month and
diff -pruN files bmake
("bmake" is the tarball's extracted directory name.)
I also just copied new files into files/ and did a "cvs diff -u"

I ended up just manually reviewing them.
But now I see that this works:
cvs diff -u -I ' \$Id: ' -I ' \$NetBSD: ' devel/bmake/files
(I now remember that I had used this in a ~/.cvsrc file before.)
And that -I switch works for normal diff too. And the -X switch is also
useful as it saves me from 187 extra lines. For example:
diff -pruN -I ' \$Id: ' -I ' \$NetBSD: ' -x CVS files bmake
