This is probably a good idea (the ".." example is arguably a Xapian bug so
that should be fixed soon, but you find all sorts of junk in message-ids.

However, the quoting feature this relies on was added in Xapian 1.0.18 (and
1.1.4), and with older versions this will break for *all* message-ids (even
those which currently work).

Also, if you're going to quote the message-id, you should escaping any "
characters in the message-id (by doubling them).
