The metadata are not used but it permits to check the symlink is valid.
We then return 1 on invalid symlinks when ls is invoked with ls -L -Z

As the existing comment says, the expected output here is dependent on
the platform, so use the `expected_result` utility to avoid hard-coding
specific results for each platform.
This fixes spurious failures on my machine.
* tests/util: Fix documentation of UCommand::stderr_only and usage_error
* tests/util: Remove trimming from CmdResult::stdout_matches and stdout_does_not_match. Fix tests.
The tests are fixed to match the trailing newline instead of ignoring it.
* ls: Implement --zero flag. (#2929)
This flag can be used to provide a easy machine parseable output from
ls, as discussed in the GNU bug report
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=49716.
There are some peculiarities with this flag:
- Current implementation of GNU ls of the `--zero` flag implies some
other flags. Those can be overridden by setting those flags after
`--zero` in the command line.
- This flag is not compatible with `--dired`. This patch is not 100%
compliant with GNU ls: GNU ls `--zero` will fail if `--dired` and
`-l` are set, while with this patch only `--dired` is needed for the
command to fail.
We also add `--dired` flag to the parser, with no additional behaviour
change.
Testing done:
```
$ bash util/build-gnu.sh

$ bash util/run-gnu-test.sh tests/ls/zero-option.sh

PASS: tests/ls/zero-option.sh

* Use the US way to spell Behavior
* Fix formatting with cargo fmt -- tests/by-util/test_ls.rs
* Simplify --zero flag overriding logic by using index_of
Also, allow multiple --zero flags, as this is possible with GNU ls
command. Only the last one is taken into account.
