The current code only skips the question if it _only has one possible
answer_ - a code path that I don't think even ever gets exercised now.

The descriptions in column 4 are not adequate, without a country, to
select a time zone. You would basically have to add the country to it. I
don't see why you're going for this nuclear option when the issue could
have been resolved simply by replacing Asia/Jerusalem with Asia/Tel_Aviv
in zone.tab with _no_ data changes (and for heaven's sake, nobody was
arguing about Taiwan... except the anti-change people using it to draw a
false equivalency).
