Change attributions for contributors' names using the Latin alphabet
only where it was possible to reconstruct from mailing list records.
Leave attributions for Андрей Чернов, Иофис Герман Романович, and 李耀
宗 with their romanized versions instead (Andrey A. Chernov, German
Iofis, and Lee Yiu Chung, respectively).
(Thanks to Garrett Wollman for reporting the problem.)
* NEWS, Theory, northamerica: Add "coding: utf-8" directives so
that GNU Emacs, when run in a unibyte locale, does not mistakenly
interpret these files to be unibyte. This change should make no
difference if you use Emacs to read these files in a UTF-8 locale.
I didn't bother to add coding directives to files where GNU Emacs
already deduces the encoding correctly in a Latin-1 locale.
Garrett Wollman reported privately that XEmacs 21.4.22, the current
stable version, doesn't work with the UTF-8 recently introduced
into our commentary. For example, the UTF-8 character '−'
(MINUS SIGN), which is stored as the three bytes "\342\210\222",
displays as 'â\210\222'. For proper names this is annoying but
tolerable, as there's little loss in utility from (say) 'Racoviță'
to its display form 'RacoviÈ\233Ä\203'. But for symbols this is a
real pain that can make it hard to understand the documentation, e.g.,
'Release 2014e – 2014-06-12 21:53:52 −0700' displays as
'Release 2014e â\200\223 2014-06-12 21:53:52 â\210\2220700'.
To work around this problem, make the following substitutions in
commentary to mostly revert these symbols to their pre-UTF-8 versions:
'§' -> 'section', '°' -> 'degrees', '±' -> '+-', '–' -> '-' (en
dash), '—' -> '--' (em dash), '′' -> "'", '″' -> '"', '→' -> '->',
'−' -> '-' (minus sign), '≤' -> '<='. Leave proper names and
foreign words in UTF-8.
Most of this patch is to commentary, to distinguish better among
the similar characters hyphen '-', minus sign '−', en dash '–' (used
for ranges), and em dash '—'. Render ordinary dashes in text as
spaced en dashes, as this gives better-looking results in monospaced
fonts.
* yearistype.sh, zic.c: Reword diagnostics so that they do not use
hyphens as if they were dashes. Since we are sticking to ASCII in
programs, we can't use proper dashes in diagnostics.
In several cases our text files had commentary like this:
# Egypt to cancel daylight saving time
# <a href="http://www.almasryalyoum.com/en/node/407168">
# http://www.almasryalyoum.com/en/node/407168
# </a>
where lines 2 and 4 let the file be viewed by a browser with the
URL being clickable. In practice this approach does not work with
many modern browsers (I tested with Firefox and with Chrome) and
it clutters up the data, so in cases like the above this patch
removes lines 2 and 4.

* northamerica (America/Cayman, America/Jamaica, America/Grand_Turk):
Change KMT from -5:07:12 to -5:07:11 (should be -5:07:10.41).
* zone.tab: Fine-tune geographical coordinates to match -5:07:10.41.
I chose the latitude to match the General Post Office, Kingston,
in the city center according to Google Maps.
* northamerica (America/Anguilla, America/Dominica, America/Grenada)
(America/Guadeloupe, America/Montserrat, America/St_Kitts)
(America/St_Lucia, America/St_Vincent, America/Tortola)
(America/St_Thomas):
Link to America/Port_of_Spain instead of having a separate zone
that differs only in LMT. Each LMT entry is just a placeholder for
unavailable info, and by itself does not justify a separate zone.
Using just one zone simplifies maintenance, makes the runtime
a bit smaller, and can help simplify user selection of zones.
* southamerica (America/Aruba): Likewise, for America/Curacao.
* backward (America/Virgin):
* northamerica (America/St_Barthelemy, America/Marigot):
Adjust to the other changes, by not linking to a link.
This should allay concerns that the links would go away any time soon.
Suggested by Stephen Colebourne in
<http://mm.icann.org/pipermail/tz/2013-September/019801.html>.
Change "`" to "'"; these days, "`" and "'" are not symmetric.
* antarctica (Antarctica/McMurdo):
* europe (Europe/Jersey, Europe/Guernsey, Europe/Isle_of_Man)
(Europe/Mariehamn, Europe/Busingen, Europe/Vatican, Europe/San_Marino)
(Arctic/Longyearbyen, Europe/Ljubljana, Europe/Podgorica)
(Europe/Sarajevo, Europe/Skopje, Europe/Zagreb, Europe/Bratislava):
* northamerica (America/St_Barthelemy, America/Marigot):
* southamerica (America/Lower_Princes, America/Kralendijk):
Move here from 'backward'. This reverts a 2013-08-09 change.
Other tz file readers had problems with the new pre1970 file, so
remove it and related changes. To recover the pre-1970 data,
instead change pre-1970 Zone entries in other files back to what
they were. Perhaps we'll try to find a better way someday.
* .gitignore: Remove back-pre1970.
* Makefile (BACKWARD): Remove. All uses changed back to 'backward'.
(AWK_SCRIPTS): Remove back-pre1970.awk.
(back-pre1970): Remove.
(clean_misc): Don't rm back-pre1970.
(check_public): Remove special case for pre1970.
* back-pre1970.awk, pre1970: Remove.
* backward (America/Anguilla, America/Antigua, America/Aruba)
(America/Atikokan, America/Blanc-Sablon, America/Cayman)
(America/Creston, America/Curacao, America/Dominica, America/Grenada)
(America/Guadeloupe, America/Montreal, America/Montserrat)
(America/Nassau, America/Port_of_Spain, America/St_Kitts)
(America/St_Lucia, America/St_Thomas, America/St_Vincent)
(America/Tortola): Remove, as these are zones again.
(America/Coral_Harbour, America/Kralendijk, America/Lower_Princes)
(America/Marigot, America/St_Barthelemy, America/Virgin):
Revert to previous links.
* northamerica (Mont, America/Blanc-Sablon, America/Montreal)
(America/Atikokan, America/Creston, America/Anguilla, America/Antigua)
(Bahamas, America/Nassau, America/Cayman, America/Dominica)
(America/Grenada, America/Guadeloupe, America/Montserrat)
(America/St_Kitts, America/St_Lucia, America/St_Vincent)
(America/Tortola, America/St_Thomas):
* southamerica (America/Aruba, America/Curacao, America/Port_of_Spain):
Restore these rules and zones.
* .gitignore: Add back-pre1970.
This is like the previous change, except it entails a change to zone.tab.
The America/Montreal entry was created only because we mistakenly
thought that Montreal's and Toronto's post-1970 time stamps differed.
* backward, northamerica (America/Montreal):
Now a 'backward' link to America/Toronto.
* northamerica (Mont): Remove rules; no longer needed.
(America/Thunder_Bay): Refer to Toronto rules, not Mont.
This doesn't change any time stamps.
* zone.tab (America/Montreal): Remove.
(America/Toronto): Say that it also covers most of Quebec.
This continues in the series of moving entries to 'backward' if
they exist only because of obsolete tz rules about country codes.
In this case, Zone entries are changed to Links; this doesn't
affect any post-1970 time stamps, and the pre-1970 time stamps
are out of scope and are often of dubious reliability.
* backward, northamerica, southamerica (America/Anguilla)
(America/Antigua, America/Aruba, America/Blanc-Sablon)
(America/Cayman, America/Curacao, America/Dominica)
(America/Grenada, America/Guadeloupe, America/Montserrat)
(America/Port_of_Spain, America/St_Kitts, America/St_Lucia)
(America/St_Thomas, America/St_Vincent, America/Tortola):
Now 'backward' links to America/Puerto_Rico.
(America/Atikokan): Now a 'backward' link to America/Panama.
(America/Creston): Now a 'backward' link to America/Phoenix.
(America/Nassau): Now a 'backward' link to America/Toronto.
* backward (America/Coral_Harbour, America/Kralendijk)
(America/Lower_Princes, America/Marigot, America/St_Barthelemy)
(America/Virgin): Adjust to avoid link-to-a-link.
This fixes the 2013-08-15 change so that 'make check' works again.
* backward (America/Shiprock): Move this link here....
* northamerica (America/Shiprock): ... to here.
* backward: Move links here from other files, if the only reason
they existed was to fill out zone.tab. Zones are now allowed to
cross national borders, so a zone now need not exist merely
because there's a national border. Sort the list consistently.
None of this changes any time stamp in the database.
* checktab.awk: Don't require that zone.tab's column 3 be unique.
* europe (Europe/Jersey, Europe/Guernsey, Europe/Isle_of_Man)
(Europe/Mariehamn, Europe/Busingen, Europe/Vatican, Europe/San_Marino)
(Arctic/Longyearbyen, Europe/Ljubljana, Europe/Podgorica)
(Europe/Sarajevo, Europe/Skopje, Europe/Zagreb, Europe/Bratislava):
* northamerica (America/St_Barthelemy, America/Marigot):
* southamerica (America/Lower_Princes, America/Kralendijk):
Move links to 'backward'.
* zone.tab: Give more details about how different rows can have
duplicate column 1 or column 3. For each link moved to 'backward',
change column 3 to be the non-backward name.
