- \r\n is common a line end combination
- catting such a file without options causes it to display normally
- overwriting the first char with $, loses info
* src/cat.c (cat): Convert \r preceeding a \n to ^M.
* tests/misc/cat-E.sh: New test.
* tests/local.mk: Reference new test.
* tests/misc/cat-proc.sh: Fix typo.
* doc/coreutils.texi (cat invocation): Mention the new behavior.
* NEWS: Mention the improvement.
* doc/coreutils.texi: Fix regexp cross-reference that had become
out-of-date (Bug#45749). Also, fix some obsolete references to
SunOS and to /usr/dict/words, and change “Linux” to “GNU/Linux”
where appropriate. Unfortunately the pipeline example gets more
complicated since /usr/share/dict/words is not sorted the way that
‘comm’ wants.
This file is a copy from gnulib and therefore should not get changed
by the yearly update.
* .x-update-copyright: Add pattern for the above file.
* doc/fdl.texi: Revert the previous change.
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.
* doc/coreutils.texi (seq invocation): Mention "inf" is supported,
and describe that it's handled specially to generate infinite
whole integer sequences. Also mention that such infinite generation
is supported for integer steps up to 200.
(sleep invocation): Give `sleep inf` as an example to sleep forever.
* src/seq.c: Add a comment on SEQ_FAST_STEP_LIMIT, to say it's
reflected in the texinfo description.
Chris Colohan wrote that the man page did not do enough to dispel
a common misunderstanding that “contributed to one of the scariest
outages Google has ever seen” (Bug#45258).
* doc/coreutils.texi (mkdir invocation):
* src/mkdir.c (usage): Document -m vs -p better.
* 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.
* doc/coreutils.texi (sort invocation): Mention explicitly
that --general-numeric-sort supports arbitrary format hex numbers,
but also mention that consistent case/width hex numbers can
be sorted faster with a standard sort.
* doc/coreutils.texi (timeout invocation): Avoid any implication
that `timeout --foreground` could be used to retroactively
timeout commands not already invoked by timeout(1).
Fixes bug https://bugs.gnu.org/42831
* doc/coreutils.texi (timeout invocation): Document that the the
duration of --kill-after=DURATION begins when sending the initial
signal. Also mention that -k does not have any effect if timeout's
duration is 0.
Suggested by Jonny Grant <jg@jguk.org>.
* doc/coreutils.texi (timeout invocation): Document that the exit
status is 137 when the KILL signal is used, regardless of whether that
signal is sent to COMMAND or timeout.
* src/timeout.c (usage): Likewise. Also split out and expand
on the possible exit status values to a separate table.

Since the previous gnulib update, bootstrap outputs this warning:
Notice from module fdl:
Don't use this module! Instead, copy the referenced license file \
into your version control repository.
See gnulib commit:
https://git.sv.gnu.org/cgit/gnulib.git/commit/?id=88fc5afbccc9
* bootstrap.conf (gnulib_modules): Remove 'fdl'.
* doc/fdl.texi: Add file as a copy of 'gnulib/doc/fdl.texi'.
* doc/.gitignore (/fdl.texi): Remove entry.
* cfg.mk (FILTER_LONG_LINES): Add pattern for the 'fdl.texi' file.
Have the `ls` `--classify` option take an optional argument for when to
classify ("always", "auto", "never"), just like the optional argument
for `--color`. When the optional argument is not specified, default to
"always" for backwards compatibility.
* src/ls.c (usage): Update help text.
(decode_switches): Support an optional argument for --classify.
* tests/ls/classify.sh: Add a new test.
* tests/local.mk: Reference the new test.
* NEWS: Mention the new feature.
* src/stat.c (usage): Mention permission bits rather than
"access" so there is no confusion with ACLs etc.
Also indicate we output the file type with '%A'.
* doc/coreutils.texi (stat invocation): Likewise.
Also indicate '%A' is similar to `ls -ld` output.
Addresses https://bugs.gnu.org/39613
* src/ls.c (usage): Reorganize help for --time,
and add description for --time=birth.
(do_statx): Store btime in mtime if available.
(get_stat_btime): A new function to read the creation time
from the appropriate stat structure member.
(cmp_btime): A new function to compare birth time.
(print_long_format): Output '?' when birth time unavailable.
* doc/coreutils.texi: Document --time={birth,creation}.
* tests/local.mk: Reference the new test.
* tests/ls/birthtime.sh: Add a new test.
* NEWS: Mention the new feature.
Run "make update-copyright" and then...
* gnulib: Update to latest with copyright year adjusted.
* tests/init.sh: Sync with gnulib to pick up copyright year.
* bootstrap: Likewise.
* tests/sample-test: Adjust to use the single most recent year.
* doc/coreutils.texi (sleep invocation): Add an example to demonstrate
how to use the floating-point and the scientific notation to sleep
for sub-second times, e.g. milli-, micro- and nanoseconds.

* doc/sort-version.texi (Minus/Hyphen and Colon characters):
Rename from “Minus/Hyphen @samp{-} and Colon @samp{:} characters”,
as texi2any 6.6 complains about colons in node names.
* doc/coreutils.texi (shred invocation):
Modernize discussion to today’s technology (Bug#38168).
* src/shred.c (usage): Omit lengthy duplication of the manual’s
discussion of file systems and storage devices, as that became out
of sync with the manual. Instead, just cite the manual.
* doc/sort-version.texi: Fix some typos, avoid overly long lines in
the generated PDF, enclose some sample strings in @samp{...} for better
readability, etc. This also avoids an sc-avoid-builtin error:
s/builtin/built-in/
* doc/sort-version.texi: New file.
* doc/local.mk (doc_coreutils_TEXINFOS): Add new file.
* doc/coreutils.texi: @include new file, replace previous "Details about
version sort" section.
* src/stat.c: Drop statbuf argument from out_epoch_sec().
Use statx() rather than [lf]stat() where available,
so a separate call is not required to get birth time.
Set STATX_* mask bits only for things we want to print,
which can be more efficient on some file systems.
Add a new --cache= command-line option that sets the appropriate hint
flags in the statx call. These are primarily used with network
file systems to indicate what level of cache coherency is desired.
The new option is available unconditionally for better portability,
and ignored where not implemented.
* doc/coreutils.texi: Add documention for --cached.
* man/stat.x (SEE ALSO): Mention statx().
* NEWS: Mention the new feature.
Very old makeinfo-4.13 fails with:
./doc/coreutils.texi:2286: Unknown command `hashchar'.
./doc/coreutils.texi:2286: Misplaced {.

Reported Bernhard Voelker in
https://lists.gnu.org/r/coreutils/2019-03/msg00016.html .
* doc/coreutils.texi (basenc invocation): Replace @hashchar{} with
actual hash character. The special syntax is only required
when referring to #line directives.
* 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
See https://bugs.gnu.org/34488#8
* NEWS: Mention new options.
* doc/coreutils.texi (env invocation): Document new options.
* man/env.x: Add example of --default-signal=SIG usage.
(SEE ALSO): Mention sigprocmask.
* src/env.c (signals): New global variable.
(longopts): Add new options.
(usage): Print new options.
(parse_signal_params): Parse comma-separated list of signals, store in
signals variable.
(reset_signal_handlers): Set each signal to SIG_DFL/SIG_IGN.
(parse_block_signal_params): Parse command-line options.
(set_signal_proc_mask): Call sigprocmask to block/unblock signals.
(main): Process new options.
* src/local.mk (src_env_SOURCES): Add operand2sig.c.
* tests/misc/env-signal-handler.sh: New test.
* tests/local.mk (all_tests): Add new test.
* doc/coreutils.texi (node seq invocation): Clarify to use the tool
'yes'; otherwise the reader may interpret the sentence as if one
could pass 'yes' as the INCREMENT value.
The recent Gnulib update fixed Bug#34608; document and test this.
* NEWS: Mention the change.
* doc/coreutils.texi (Padding and other flags):
Update doc to cover new flag and other POSIX.1-2017 changes.
* tests/misc/date.pl (date-century-plus): New test.
