If .domain.com, .sub.domain.com, and .domain-some.com were defined,
then .sub.domain.com was matched by .domain.com: wildcard names hash
was built incorrectly due to sorting order issue of "." vs "-".
They were sorted as
com.domain com.domain-some com.domain.sub
while they should be sorted as
com.domain com.domain.sub com.domain-some
for correct hash building
