new ISO 3166-1 entries

[Chuck Soper]

I recently read ISO 3166-1 Newsletter No. V-11 (2006-03-29) and 
noticed three new ISO 3166-1 entries:

GUERNSEY; GG
ISLE OF MAN;IM
JERSEY;JE

I found this rule in the Theory file:
Include at least one location per time zone rule set per country.
	One such location is enough.  Use ISO 3166 (see the file
	iso3166.tab) to help decide whether something is a country.
	However, uninhabited ISO 3166 regions like Bouvet Island
	do not need locations, since local time is not defined there.

For tzdata, should all populated ISO 3166 regions be included? Does 
this mean that three new TZ zone descriptions should be added to 
zone.tab and appropriate data files? Or, should Europe/London be used 
instead?

Should iso3166.tab be updated?
