[GL #1928]
- With query minimization enabled, named failed to resolve ip6.arpa. names
that had more labels before the IPv6 part. For example, when named
implemented query minimization on a name like
``A.B.1.2.3.4.(...).ip6.arpa.``, it stopped at the left-most IPv6 label, i.e.
``1.2.3.4.(...).ip6.arpa.`` without considering the extra labels ``A.B``.
That caused a query loop when resolving the name: if named received
NXDOMAIN answers, then the same query was repeatedly sent until the number
of queries sent reached the value in the ``max-recursion-queries``
configuration option. [GL #1847]
