Subject: [PATCH] notmuch.el: Add bindings for scrolling to notmuch-search
 mode.

We turn on the scroll-preserve-screen-position option which seems
like what's desired here, (though that's not what I normally use
when editing files---but I think scrolling through a list of email
threads is different).
