Subject: [PROPOSED 1/3] Loosen zone.tab checking for links
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

* checktab.awk: Don’t require every zone.tab entry to
be in the primary ydata, as it’s OK for these entries
to be backward-compatibility links in the ‘backward’ file.
