From review: EET and WET link to Athens and Lisbon but name clock rules,
not Greece or Portugal, so they and the other rule names (CET, EST5EDT, …)
send nothing. Pacific/Johnston has left zone.tab, which made its Honolulu
group look only American; it's set to UM by hand.

From review: tzdata links an old name to any zone with the same clocks,
even in another country (Africa/Asmera, Eritrea, links to Africa/Nairobi).
An old name now gets a country only when every zone sharing its target is
in that country, or when it's a hand-checked old name for a place listed in
zone.tab. The rest (UTC, CET, GMT, …) send nothing. Every zone Node's ICU
reports has an entry.

From review: the time zone setting could hold any text (a TZ like
home/alex/private passed the name check), so the app now looks the zone up
in a table made from the tz database (scripts/timezones.py) and sends only
its two-letter country; anything not in the table sends nothing.
Turning a setting on no longer counts as having seen the new notice, and
the country is taken out at send time until it has been, so it can't
leave early whatever order things happen in.
