[PATCH 0/2] Update search results when tags change

[Vladimir Panteleev]

One of the things that stood out to me right after I tried using
notmuch, is that whenever I performed a search (which included some
unread messages), opened an unread search result, and went back to the
search buffer, it would still show that thread as unread. To update
the display, I'd need to invoke notmuch-refresh-this-buffer, which is
not only pretty slow, but also resets point, i.e. all-in-all rather
annoying.

Fortunately, this was very easy to fix, as the machinery for updating
individual search results was already in place.
