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.
* localtime.c (time1): Shrink size of 'types' local back down
from TZ_MAX_TIMES to TZ_MAX_TYPES. The smaller value suffices,
since nseen can grow to at most TZ_MAX_TYPES. (Thanks to
Arthur David Olson.)
* NEWS: Remove mention of non-fix.
(Thanks to Milamber Space Network.)
* africa (Morocco): 2014 transitions are Jun 28 03:00 and Aug 2 02:00.
Guess a similar pattern for future years. Fix white space to be
more consistent.
* NEWS: Document this.
* africa (Egypt): 2014 transitions are June 26 and July 31 at 24:00.
(Thanks to Imed Chihi.) Guess a similar pattern for future years,
namely, DST is not observed in Ramadan, nor in the days following the
last Thursday before Ramadan, nor in the days preceding the first
Friday after Ramadan.
* NEWS: Document this.
This should help forestall flame wars among competing camps of physicists.
(Thanks to James Cloos.)
* NEWS, zic.8 (NOTES): Document this.
* zic.c (BIG_BANG): Use - 2**59 rather than a more-precise estimate.
* zic.c (inleap): Reject leap seconds preceding big_bang_time.
(Thanks to Arthur David Olson.) Also, remove redundant test and cast.

This works around Gnome bug 730332
<https://bugzilla.gnome.org/show_bug.cgi?id=730332>.
zic 2014c introduced the idea of generating a transition at the
minimum time value -2**63, to avoid ambiguities about what to do
before the first real transition. Through Glib release 2.40, the
interval_end function of Glib's gtimezone.c subtracts one from
this, to find the end time of the zeroth interval (i.e., the
interval containing all the "early" time stamps); this subtraction
typically overflows and wraps around to 2**63 - 1, which causes
Glib to go off the rails and assume that all time stamps are
"early". For example, Glib computes Sao Paulo time stamps as if
Brazil's circa-1913 rules were still in effect.
(Thanks to Leonardo Chiquitto for reporting the bug.)
Work around the bug by not generating time stamps equal to -2**63.
Come to think of it, time stamps before the Big Bang are physically
suspect anyway, so don't generate time stamps before the Big Bang.
* Makefile (GCC_DEBUG_FLAGS): Add comment re BIG_BANG.
* NEWS, zic.8 (NOTES): Document this.
* zic.c (BIG_BANG): New macro.
(big_bang_time): New constant.
(writezone, outzone, addtt): Compare to big_bang_time, not to
min_time, when deciding whether to output a time stamp.
(Thanks to Ahmad El-Dardiry.)
* NEWS: Document this.
* africa (Egypt): Add rules for 2014 through 2038. They all
involve some guesswork, unfortunately.
* antarctica (Antarctica/Troll), NEWS: Uncomment, but with an
approximation that uses only UTC and CEST. (Thanks to Bengt-Inge
Larsson.)
* zone.tab (Antarctica/Troll): New entry.
This lets zic handle the time rules of Troll station,
Antarctica. Adapted from a fix by Zefram in:
http://mm.icann.org/pipermail/tz/2014-March/020759.html
* zic.c (timecnt_alloc): New static var.
(attypes): Now a pointer to an array, not a fixed size array.
(writezone, addtt): Don't assume the number of times is less than
TZ_MAX_TIMES.
* NEWS: Document this.
* europe (Europe/Simferopol), NEWS:
Crimea switches to MSK on 2014-03-30 at 02:00 local time.

* zone.tab: Move its zone.tab entry from UA to RU.
* tz-link.htm, NEWS: Fix misstatement about which part of the
Microsoft Windows software universe supports tz database names.
(Thanks to Donald MacQueen.)
* tz-link.htm, NEWS: Add Time.is (thanks to Even Scharning), WX-now
(thanks to David Braverman), TZ4Net (thanks to Matt Johnson).
Remove Simple Timer + Clocks.
* tz-link.htm: Mention zeitverschiebung.net (thanks to Martin
Jaeger) and the timezone-olson Haskell package. Remove moribund
