Those names were put into zone.tab in error, as they didn't
follow the rules given in Theory (not the current stable rules,
nor the currently-proposed rules, nor even the older rules).
We need to be able to correct errors in the database;
stability doesn't trump fixing mistakes.

On the contrary, it's a win from the human perspective.
First, it simplifies the choice of TZ, by removing irrelevant
choices.  Second, for this particular example, the folks in
the South Pole are well aware that they keep New Zealand time,
since that's where they get their supplies from, and so this
change will match their human perspective.

Longstanding practice has been to avoid links-to-links;
otherwise zic can misbehave.
