* NEWS: Mention the improvement.
* src/nl.c: Include mcel.h.
(DEFAULT_SECTION_DELIMITERS): Resize to fit 2 multi-byte characters.
(section_del_len): New variable.
(check_section): Compare against section_del_len instead of 2.
(main): Support multi-byte characters for the -d option.
* tests/nl/multibyte.sh: New file.
* tests/nl/nl.sh: New file, moved from tests/misc/nl.sh.
* tests/local.mk (all_tests): Add the new test. Adjust the existing
tests file name.
* cfg.mk (exclude_file_name_regexp--sc_space_tab): Adjust Adjust the
existing tests file name.
With dash as /bin/sh, you get the error
```
checking for sys/capability.h... yes
./configure: 95775: test: no: unexpected operator
checking for working fork... yes
```
* configure.ac: Use '=' in test for equality, not '==',
for POSIX shell compatibility.
* NEWS: Mention the build fix.
The assign to next_tab_column in the backspace branch is never
read; in fact it's always written and then read solely inside the
blank branch.
Move the declaration of 'next_tab_column' down into the blank
branch, and remove its assignment in the backspace branch.
Spotted by the 'infer' static checker.
* src/unexpand.c (unexpand): Remove dead store of next_tab_column.
A user that had an environment with SHELL=/usr/bin/fish
reported the following when trying to build info docs:
build-aux/missing (line 4): Unsupported use of '='. In fish
* doc/local.mk: Propagate make's SHELL to our
makeinfo wrapper, so that the substituted ${SHELL}
uses a compatible shell from the Makefile.
Make this change temporarily in coreutils.
Move to gnulib after v9.10 is released.
* top/maint.mk (web-manual): Propagate MAKEINFO explicitly,
rather than requiring it exported in the environment,
which can be awkward on Solaris make for example.
* src/system.h (oputs_): Ensure we're not matching '-' in
translated descriptions. Also support highlighting only
dd "foo=bar" when the description is separated with a single space.
* src/system.h (oputs_): Translations sometimes use a single space
between an option and its description. They only do this though
for long options since they result in less available screen space.
Therefore be more strict with option matching once we've encountered
a long option, which supports the more varied formats often
associated with short options.
Font problem reported by Michael Aramini via Alejandro Colomar
<https://bugs.gnu.org/80258>. This patch also fixes some
longstanding confusion with date synopses.
* src/date.c (usage): Do not imply that only -u can be used with
MMDDhhmm..., and do not put misleading brackets around the latter.
* tests/chgrp/from.sh: If 'id' cannot find a user name for user id 1,
expect the user id to be printed in the message of 'chgrp'.
Reported by Bruno Haible.
tail(1) could fail with an "Interrupted system call"
diagnostic, on some systems like Centos 5 (Linux 2.6.18).
This was seen with tests/tail/overlay-headers.sh
which sends SIGCONT, which should not induce a failure.
* src/tail.c (tail_forever_inotify): Retry the poll()
upon receiving a non terminating signal, and the syscall
is not automatically restarted by the system.
* NEWS: Mention the bug fix.
Reported by Bruno Haible.
This fixes test failures seen on Haiku.
* tests/ls/recursive.sh: Run 'ls' even if ulimit fails.
* tests/split/r-chunk.sh: Run 'split' even if ulimit fails.
* tests/sort/sort-merge-fdlimit.sh: Skip test if 'ulimit -n' cannot set
file descriptor limits.
Reported by Bruno Haible.
* src/nproc.c (usage): Clarify the impact of 'OMP_NUM_THREADS'
and 'OMP_THREAD_LIMIT' in --help and the man page.
Also mention that nproc(1) will always return > 0.
