* Makefile (check_character_set): Don't require iso3166.tab
to be ASCII.
* NEWS: Document this.
* iso3166.tab (AX, CI, RE): Use UTF-8 rather than ASCII approximations.
It allows multiple country codes per zone. Switch code and data to
use the new format, along with the recently-added Crozet Islands entry.
The old zone.tab file is still installed but is deprecated.
The new file uses UTF-8; add commentary saying that iso3166.tab is
planned to change to UTF-8.
* Theory, tzselect.8 (FILES): zone.tab -> time.tab.
* africa (Indian/Alfred_Faure): Remove link.
* antarctica: Mention Possession Island in comments.
* checktab.awk: Add support for checking time.tab.
* iso3166.tab: Mention planned switch to UTF-8.
Update ISO 3166-1 Newsletter from VI-15 to VI-16.
* time.tab: New file.
* tzselect.ksh (zonetabtype): New variable.
Add undocumented -t option, meant for developer testing.
(TZ_ZONE_TABLE): Use zonetabtype.
(output_distances, countries, regions, TZ): Support time.tab format.
(quoted_continents, distance_table, countries, regions)
(TZ, TZ_for_date): Quote shell strings more carefully.
* zone.tab: Refer to time.tab for detailed comments about format.
(Indian/Alfred_Faure): Remove.
* Makefile (TIMETABLES): New macro.
(TABDATA, install, check_tables): Use it.
(check_character_set, check_tables): Check time.tab too.
(check_time_t_alternatives): Use time.tab, not zone.tab.
* NEWS: Document the above.
This was appropriate before Unicode, where "`" and "'" often balanced
in visual output, but that's been obsolete for a while.
Overall, single-quote 'like this' instead of `like this', and
double-quote "like this" or (in typeset output) “like this”
instead of ``like this''. While we're at it, fix some glitches
with hyphens versus minus versus en dash versus em dash.
* Makefile ($(MANTXTS)): Use UTF-8 locale to produce *.txt output.
* checktab.awk, tzselect.ksh:
Quote 'like this' in diagnostics, instead of `like this'.
* date.1, newctime.3, newtzset.3, time2posix.3, zic.8 (q, lq, rq):
New macros. Use them for better double-quoting in output.
* workman.sh: Tell Perl that its stdin and stdout are UTF-8.
* NEWS: Document this.
* iso3166.tab, zone.tab: Make it clear that country codes aren't
necessarily for countries. Thanks to Derick Rethans for spotting this.

Undo recent changes, going back to the way these entries were done
in the last tz distribution. Only the Antarctica/South_Pole change
was retained.
This change stemmed from a long discussion on the tz mailing list
about what country the Jerusalem zone entry is in. The idea of
this change is to deemphasize the role of countries in the tz
database, to lessen the amount of controversy in the future.
Due to backward compatibility concerns this change does not eliminate
the role of countries entirely. With one minor exception this
change does not alter any code or data, just comments.
* Theory, zone.tab: Deemphasize the role of countries in choosing
location names, as they tend to introduce political conflict
during maintenance, and country information isn't needed for
typical uses of the database.
* Theory: Say that names should differ in more than just case, and why;
and explain why 'backward' means old names will continue to work.
(thanks to Norbert Lindenberg for spotting these issues).
Update citation date and URL.
* iso3166.tab: Mention latest maintenance update.
Update citation URL. Add missing comma for BQ.
Be more consistent about abbreviating Sint like Saint.
Mention SX "Dutch part" for consistency with MF "French part".
* iso3166.tab, zone.tab: Add legal/territorial disclaimer.
* zone.tab: Say that country/zone overlaps can occur in both
directions, and that column 2 need not lie within column 1.
(Asia/Jerusalem): Change the coordinates from a sloppy value,
taken from an old astrology book, to a more-precise value, the
site of city hall. The sloppy value sparked some controversy and
the hope is that the more-precise value will be a bit less
controversial.
