Nifty.  I wonder what input methods OS folks will stick on the front
of that.  Probably not many of the general public can reel off their
geographical coordinates, numerically, to within a degree.  (But then
this code doesn't require the input to be accurate even as coarsely as
a degree.)

I think tzselect only needs to handle the forms actually seen in zone.tab.
The format notes at the top of zone.tab explicitly limit it to two of
the formats that ISO 6709 permits.  (Still would be *nice* to handle all
ISO 6709 cases, and, separately, even nicer to detect unsupported/invalid
formats.)
