Report errors properly instead of panicking.
Replace zero_copy by a simpler specialized private module.
Do not assume splices move all data at once.
Use the modern uutils machinery.
Remove the "latency" feature. The time it takes to prepare the buffer
is drowned out by the startup time anyway.
yes: Add tests
yes: Fix long input test on Windows
Fix a bug in `tac` where multi-character line separators would cause
incorrect behavior when there was overlap between candidate matches in
the input string. This commit adds a dependency on `memchr` in order to
use the `memchr::memmem::rfind_iter()` function to scan for
non-overlapping instances of the specified line separator characters,
scanning from right to left.
Fixes#2580.
* hashsum: support --check for var. length outputs
Add the ability for `hashsum --check` to work with algorithms with
variable output length. Previously, the program would terminate with an
error due to constructing an invalid regular expression.
* fixup! hashsum: support --check for var. length outputs
* tac: correct behavior of -b option
Correct the behavior of `tac -b` to match that of GNU coreutils
`tac`. Specifically, this changes `tac -b` to assume *leading* line
separators instead of the default *trailing* line separators.
Before this commit, the (incorrect) behavior was
$ printf "/abc/def" | tac -b -s "/"
def/abc/
After this commit, the behavior is
$ printf "/abc/def" | tac -b -s "/"
/def/abc
Fixes#2262.

Setting the current directory in tests affects other tests, even if the
change is reverted after, because tests are run in parallel.
This should fix the flaky cp tests.
Since some tests run multiple commands, we have to re-calculate the
expected result for every run.
This is because the expected results depend on file timestamps, but the
files are re-created for every new TestScenario.
If options::WIDTH is not given, we should try to use the terminal width.
If that is unavailable, we should fall back to the 'COLUMNS' environment variable.
If that is unavailable (or invalid), we should fall back to a default of 80.
The following test case read stdin instead of file:
```
echo abcdefg > file
cargo run -- od --format x1 file
```
This is because the -t/--format argument was able to absorb multiple
arguments after it. This has now been fixed, and a test case is added
to ensure it will not happen again.
When hitting Ctrl+C sort now deletes any temporary files. To make this easier I
created a new struct `TmpDirWrapper` that handles the creation of new temporary
files and the registration of the signal handler.
The ToDo list was updated to mark `chcon` as done.
Building and testing `chcon` requires enabling the `feat_selinux` feature. If `make` is used for building, then please specify `SELINUX_ENABLED=1` if building and testing on a system where SELinux is not enabled.
