One could parse the X-Labels header and compare it with actual tags
given message has.  If there are some tags that X-Labels lists but the
message does not have, the notmuch->gmail syncing tool could assume that
those were removed by notmuch.  Similarly with tags that are not in
X-Labels but the message has.  (Of course the list of tags would have to
be limited to those that have corresponding gmail labels.)  Just
a thought.
