Named automatically sets up "empty" reverse zones for nonroutable
address spaces, to prevent your network sending PTR queries
out for things like 10.1.2.3, which can only be configured locally.

These zones were interacting badly forward-only zones.  For example,
if you set up a forward zone for 100.10.in-addr.arpa, which is beneath
the empty zone 10.in-addr.arpa, PTR queries for 10.100.*.* should be
forwarded while all other queries for 10.* should be answered from
the empty zone.  That wasn't working; now it is.
