Nested wildcards not handled properly #794

Hello,

I think this relates to some of the prior issues I filed earlier but want to make sure there is a simple example to follow.

Consider the zone file:

test.     500     IN      SOA     ns1.outside.edu. root.campus.edu. 3 6048 4000 2419200 6048
test.     500     IN      NS      ns1.outside.edu.
*.test.   500     IN      A       11.1.1.1
*.*.test. 500     IN      A       12.2.2.2

For the query foo.*.test, the Technitium server returns 11.1.1.1, but ideally it should return the 12.2.2.2 address.

Detail description of wildcard closest encloser can be found in the RFC - https://www.rfc-editor.org/rfc/rfc4592#section-2.2.1

Thanks, Siva
