Back on the subject of Jerusalem...

While looking up some information about ISO 3166 for background for this
discussion, I noticed that ISO 3166-2 lists "Jerusalem" regions for both
countries: IL-JM and PS-JEM. If we _must_ list Jerusalem in zone.tab
(rather than simply using Tel_Aviv and Ramallah, respectively, which I
still think is the best solution as it simply avoids making any
comment), maybe it should therefore be listed in both.

(ISO 3166-2 also lists Taiwan as CN-71, though it does not list the
mainland territories administered by the PRC under TW - this would
suggest listing Asia/Taipei under both countries, but not Asia/Beijing.)
