But the real point here is that we _want_ some of the backward zones -
especially the ones that users may have legitimately configured with
tzsetup (which reads zone.tab / zone1970.tab) in the past but which got
renamed (as in the recent example of America/Godthab).
The problem right now is that there isn't a way to conveniently
distinguish those zones from the ones that just get in the way and cause
confusion. This is why my proposal retains in the "backward" file every
zone that has ever been in zone.tab.
