In particular, this patch is makes the commentary more systematic
about preferring "time zone" to "timezone" except when quoting someone
else or when talking about code that uses "timezone".
This should better address concerns about large-scale changes.
We can do the rest of these changes later, as they're not urgent.

"Metlakatla Time". Cite the news report in the commentary,
and quote some Juneau graffiti.

11-01, not 11-03; in 1941 the transition to DST was 04-08 not
04-06 at 02:00; and there was no DST in 1920.

Remove zone, replacing each with a link to a region that has had
the same UTC offset since 1970. This removes data that were
largely invented, either by us or almost surely by Shanks or his
sources.
* asia, australasia, northamerica: Create links accordingly.

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.
