One side effect of this seems to be a regression, namely that in the
current buffer the "visual history" of tag changes is broken. Previously
deletions were shown by red strike-through and additions by green
underline. The deletions are now removed by the global update, and
additions shown on the wrong tags.

Another aspect that is a bit surprising is that it doesn't change whether
threads actually match. For example if I have search for tag:inbox,
adding tag inbox to a thread won't cause the corresponding thread to
show up. This is maybe defensible, but it wasn't clear to me if it was
intentional.
