103d2b92da maint: modernize URLs
A lot of this is converting http: to https:.
Also, gmane went away, so remove URLs that no longer work and
are not easy to figure out what they were.
Some of this stuff is so old that it no longer matters anyway.

Specifically there would be invalid memory access

was beyond the initial amount read from file (which is
currently capped at 128KiB).  This issue is not in a
released version, only being introduced in commit v8.25-4-g62e7af0

f04daf570b tail: -F now always processes initially untailable files
which was not the case when inotify was not available.

* src/tail.c (any_live_files): Simplify, since the IGNORE
flag is now only set when a file should be ignored indefinitely.
(recheck): Only output the "giving up on name" message
when that's actually the case.  Only set the IGNORE flag
when ignoring a file indefinitely.
(tail_file): Likewise.
* tests/tail-2/retry.sh: Add a test case.  Also run
all existing test cases with and without inotify.
NEWS: Mention the fix.
THANKS.in: Add the reporter.

the course of the SYMBIOSYS research project at
COMSYS, RWTH Aachen University.

1db94ee969 ls: fix %%b format and precompute more
The old code mishandled --time-spec='+%%b', as it misinterpreted
the '%b' as being the month abbreviation.  Also, it mishandled
the extremely unlikely case of a month abbreviation containing '%'.
The performance part of this patch sped up 'ls' by about 1% on my
little benchmark of 'ls -lR' on the source directory in the
en_US.UTF-8 locale (Fedora 24 x86-64).
* NEWS: Document the bug fix.
* src/ls.c (first_percent_b, abformat_init): New static functions.
(ABFORMAT_SIZE): New constant.
(use_abformat): New static var.
(abmon, required_mon_width): Remove these static vars.
(abmon_init): Now accepts a pointer to abmon, and returns a boolean.
All callers changed.  Reject month abbrs containing '%', as these
would mess up strftime.  Simplify mbsalign result checking,
since (size_t) -1 exceeds ABFORMAT_SIZE.
(abformat_init, align_nstrftime): Precompute all 24 formats at
startup, rather than computing a format for each time stamp.
(decode_switches): Call abformat_init instead of abmon_init.
(align_nstrftime): Accept recentness bool instead of format.
All callers changed.
* tests/misc/time-style.sh: Test for format with '%%b'.

c6389a1340 date: add '--debug' option
Usage example:
    date --debug -d 'now + 3 days'

Print parsing and debugging information to stderr when using date's
-d/--date option.
See: http://lists.gnu.org/archive/html/coreutils/2016-01/msg00076.html

* src/date.c (main): Add '--debug' option, enable debugging
in gnulib's parse-datetime.y module.
* tests/misc/date.pl: Repeat tests with '--debug' enable, ensure
no regression.
* tests/misc/date-debug.sh: Test output of '--debug' option.
* tests/local.mk: Add above test.
* NEWS: Mention new option.
* doc/coreutils.texi: Likewise.
