also makes it easier for us to maintain a consistent
header/footer across our HTML.

Subject: view: tweak thread/index header slightly

This makes the top permalink/raw as well as the In-Reply-To
show up without search.  While we're at it, try to make
the links on the thread index from the "X siblings, Y replies"
more obvious.

This hybrid view is better than the old flat, but can
still fall down compared to the old threaded view in
some cases.
