[PATCH 6/7] emacs: search: use orig-tags in search

[Mark Walters]

This uses the recent functionality to show the tag changes in the
search buffer. Currently this is only used to show changes the search
buffer makes itself: i.e., it does not make display any changes
reflecting tagging done by other notmuch-buffers.
