 While trying to use some BIND 9 tests, I found a strange behavior of
 b10-auth.

 Consider b10-auth (with sqlite3 data source) configured as serving
 both root and net.

 In the root zone it has the following delegation (+glue):
 {{{
 example.                        172800  IN      NS      ns.example.
 example.                        172800  IN      NS      ns1.example.net.
 ns.example.                     172800  IN      A       192.0.2.1
 ns1.example.net.                172800  IN      A       192.0.2.3
 }}}

 In the net zone, it has the following:
 {{{
 example.net.                    NS      ns1.example.info.
 example.net.                    NS      ns2.example.info.
 }}}

 With this setup, if we query for foo.example, b10-auth returns a
 response with an empty additional section.

 BIND 9 returns both of the two A RRs.

 b10-auth should also return at least the flue for ns.example.

 For reference, I'm attaching the test zone files and sqlite3 DB
 generated from them that I used for the test.
