[PATCH v2 7/7] emacs: tree: use orig-tags in search

[Mark Walters]

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