Thanks; patch applied to Emacs 29.

The outline button stuff is still a work in progress, as you've found
out.  I'm not quite sure whether it should be switched on by default in
NEWS buffers -- it doesn't seem to bring much value there.  (As opposed
to in `describe-bindings', where it seems very helpful (since we're
starting out with some parts already folded.)

So I'm pondering whether to add an additional mechanism to say whether a
mode is "opting in" to the buttons or not, but I'm not sure what that
should look like.
