    Document that nsupdate does not support relative names

    The zone command in nsupdate resembles $ORIGIN in a zone file, so it is
    easy to assume that a name without a trailing dot gets the zone name
    appended. It does not: nsupdate treats every name as absolute, and the
    server then rejects the update with NOTZONE. Say so in the man page.

    If no ``zone`` statement is provided, :program:`nsupdate` attempts to
    determine the correct zone to update based on the rest of the input.

+   This command does not set an origin for names in update or prerequisite
+   commands. :program:`nsupdate` does not support zone-relative names: a name

 ``class classname``
    This command specifies the default class. If no ``class`` is specified, the default
    class is ``IN``.
