* src/nl.c (main): Enforce the POSIX specified
behavior of assuming ':' is specified after a single
character argument to -d.
* tests/misc/nl.sh: Add a test case.
* NEWS: Mention the bug fix.
* doc/coreutils.texi (nl invocation): Mention the GNU extensions
of allowing arbitrary length and empty delimiter strings.
* src/nl.c (usage): Likewise.
* tests/misc/nl.sh: Add test cases for the GNU extensions.
The format can be determined from --options or the locale,
so it's useful to output the format string being used.
* src/date.c (show_date): Show the output format

Addresses https://bugs.gnu.org/44960
This crash was identified by Cyber Independent Testing Lab:
https://cyber-itl.org/2020/10/28/citl-7000-defects.html
and was introduced with commit v8.5-163-g3f48829c2
* src/tr.c (validate_case_classes): Don't apply these
extra case alignment checks in the --complement case,
which is even more restrictive as to the contents of SET2.
* tests/misc/tr-case-class.sh: Add a test case,
for a large SET1, which caused the length adjustment
in validate_case_classes to underflow and trigger the assert.
* NEWS: Mention the bug fix.
Previously we would have failed immediately upon internal overflow,
which didn't output the full line being processed, and assumed
there would be another numbered line.
* src/nl.c (line_no_overflow): A new global to track overflow.
(print_lineno): Only fail if about to output an overflowed number.
(reset_lineno): A new function to refactor resetting of the number,
and which also clears line_no_overflow.
* tests/misc/nl.sh: Add a test case.
* src/csplit.c (process_regexp): Process the line suppression
in all invocations so that the last match is suppressed.
Previously with a non infinite match count,
the last regex pattern was not suppressed.
* NEWS: Mention the bug fix.
* tests/misc/csplit-suppress-matched.pl: Add a test case.
Fixes https://bugs.gnu.org/42764
* src/factor.c (strto2uintmax): Instead of here ...
(print_factors): ... skip spaces and '+' here, so that
bignums are treated like non-bignums.
* tests/misc/factor.pl (bug-gmp-plus_2_sup_128_plus_1): New test.
Since -LONG_MIN results in LONG_MIN again, the operation itself is
a signed integer overflow.
This can be observed with the following calls (best if compiled
with -ftrapv or -fsanitize=undefined):
$ numfmt --padding=-9223372036854775808
$ seq 1e-9223372036854775808
Technically, the change in seq "reduces" the precision, but a double
or long double that small would be represented as 0 anyway.
* src/numfmt.c: Explicitly disallow --padding=LONG_MIN.
* src/seq.c: Treat 1e$LONG_MIN as 1e-$LONG_MAX.
* tests/misc/numfmt.pl: Add a test case.
* tests/misc/seq-precision.sh: Likewise.
Fixes https://bugs.gnu.org/41850
* tests/misc/env-S.pl: `env -i env` will call the system env
due to the path being cleared, so pass the absolute path
of our env binary under test to avoid that. This was seen
to be an issue on Guix where /usr/bin/env was not available.
* tests/misc/timeout-parameters.sh: Split the large timeout
handling to ...
* tests/misc/timeout-large-parameters.sh: ... here, so that
the 3 second delay is contained in its own test, and if
the test is skipped due invalid handling within timeout(1),
it will be more apparent.
Also adjust the check so we skip whenever the kernel timer
fires immediately, to handle the buggy OpenIndiana 11 kernel also.
Reported by Bruno Haible.
* init.cfg (require_bash_as_SHELL_): A new function to replace
SHELL for the current test, with bash if available.
This is useful on OpenIndiana 11 where /bin/sh was seen
to have races in handling of SIGPIPE.
* tests/misc/seq-epipe.sh: Use the new function to enforce bash.
* tests/misc/env-signal-handler.sh: Likewise.
Reported by Bruno Haible
strcoll() is only significant to uniq(1) if it returns 0,
and it generally only does so with buggy locales or mismatched
locales and data. Some systems may have strcoll()
return 0 for equivalent normalized unicode forms,
but for consistency across platforms strcoll() is avoided.
The various cases are defined in the new test.
This is consistent with newer POSIX standards as discussed at:

* src/uniq.c: s/xstrcoll/memcmp/.
* tests/local.mk: Reference the new test.
* tests/misc/uniq-collate.sh: Add a new test.

‘shuf -r -n 0 file’ would mistakenly read from standard input.
Problem reported by my student Jingnong Qu while reimplementing a
shuf subset in Python as an exercise in UCLA Computer Science 35L:
https://web.cs.ucla.edu/classes/fall19/cs35L/assign/assign3.html
* NEWS: Mention the fix. Also, ASCIIfy a previous item.
* src/shuf.c (main): Fix bug.
* tests/misc/shuf.sh: Add a test case for the bug.
* src/seq.c: (seq_fast): Accept STEP as a parameter and use that
to skip the output of generated numbers.
(main): Relax to using seq_fast for integer steps between 1 and 200.
For larger steps the throughput was faster using the standard
incrementing procedure.
(cmp): Use the equivalent but faster memcmp for equal len strings.
* tests/misc/seq.pl: Update fast path cases.

Under certain circumstances seq prints an extra line when the output
format has custom format with characters following the printed numbers:
$ seq -f "%g " 1000000 1000000
1e+06
1e+06
This is due to the "print_extra_number" logic using strings to determine
whether a 'extra number' is needed, but only one string was trimmed
when using a custom printf format.
Prompted by https://lists.gnu.org/r/coreutils/2019-08/msg00001.html
* NEWS: Mention fix.
* src/seq.c (print_numbers): Trim the 'x0_str' string before comparing
it to the previous 'x_str' string.
* tests/misc/seq-extra-number.sh: Add this scenario.
* tests/local.mk (all_tests): Add new test.
When debugging an invalid date due to DST switching, the intermediate
'normalized time' should not be checked - its value can differ between
systems (e.g. glibc vs musl).

* tests/misc/date-debug.sh: Replace the exact normalized time
with 'XX:XX:XX' so different values would not trigger test failure.
* tests/misc/test-N.sh: The subsecond values for atime and mtime
were potentially seen to differ on newlyl created files.
So we include the subsecond portion when comparing stat values.
* tests/misc/wc-nbsp.sh: Add gating checks for all characters,
as there are disparate classifications on various systems:
SunOS 5.10 treats \u202F, \u2060 as !iswprint()
SunOS 5.10 treats \u00A0, \u2007 as iswspace()
AIX 7.2, Darwin 17.4.0, NetBSD 7.1 treat \u2060 as !iswprint()
Testing by Assaf Gordon on OSX showed the atime wasn't
being updated when explicitly set back in time.
Also Debian 8.11 / mips64 was seen to not update the
mtime when truncating an empty file.
* tests/misc/test-N.sh: Isolate from different timestamping
behaviors of various (file) systems, by correlating
the timestamps with stat(1) before using `test -N`.
* tests/misc/wc-nbsp.sh: FreeBSD and OS X don't
treat non breaking space as printable characters.
So use wc -L to determine printability before
testing non breaking space functionality.
* src/env.c (main): Output blocked or ignored signals
before a command is executed.
* doc/coreutils.texi (env invocation): Add the option.
* tests/misc/env-signal-handler.sh: Add a test case.
* NEWS: Mention the new feature.
New options to set signal handlers for the command being executed.
--block-signal suggested by Paul Eggert in http://bugs.gnu.org/34488#71
--default-signal is useful to overcome the POSIX limitation that shell
must not override inherited signal state, e.g. the second 'trap' here is
a no-op:
trap '' PIPE && sh -c 'trap - PIPE ; seq inf | head -n1'
Instead use:
trap '' PIPE && sh -c 'env --default-signal=PIPE seq inf | head -n1'
Similarly, the following will prevent CTRL-C from terminating the
program:
env --ignore-signal=INT seq inf > /dev/null

For select programs which accept only --help and --version options
(in addition to non-option arguments), process these options before
any other options.
Before:

$ yes me --help

Remove the function 'test_unop', as the cases therein are redundant to

they had been present in test_unop and handling the commands
test -N STR
test -o STR
and
test x = x -a -N STR
test x = x -a -o STR
which ran into an error later on anyway.
With this commit, the error diagnostic will change from ...
$ /usr/bin/test -N STR
/usr/bin/test: extra argument '-N'
$ /usr/bin/test -o STR
/usr/bin/test: extra argument '-o'
