Make `tsort` split on any whitespace character instead of just
whitespace within a single line. This allows edge information to be
split with the source node on one line and the target node on another.
For example, after this commit
$ printf "a\nb\n" | tsort
a
b
whereas before this would print an error message.
Closes#7077
Fix the parsing of the `--userspec=USER:GROUP` argument so that the
both the user and the group are optional, and update the error message
to match that of GNU `chroot`. This commit also removes the incorrect
`clap` arguments for `--user` and `--group`. In `chroot --user=USER`,
the `--user` is an abbreviation of `--userspec`, and in `chroot
--group=GROUP`, the `--group` is an abbreviation of `--groups`.
Closes#7040.
This change resolves issues with exponent calculation and usage,
ensuring more accurate formatting:
- Exponent for negative values can differ from 0
- Switching to decimal mode now follows the P > X ≥ −4 rule
* Added error handling to ensure '=' after -u returns 125 as '=' is not allowed
* Added tests for disallow = on short options
* Added error handling to ensure '=' after -u returns 125 as '=' is not allowed
* Added tests for disallow = on short options
* Disallow only short unset option from having '=' as its starting character
* Remove needless tests and update function name for clarity
Fix a subtraction underflow that occurred on `head --bytes=-N` when the
input had fewer than `N` bytes. Before this commit,
printf "a" | head -c -2
would panic. After this commit, it terminates successfully with no
output as expected.
Improve the error message produced by `seq` when given invalid format
specifiers for the `-f` option. Before this commit:
$ seq -f "%" 1
seq: %: invalid conversion specification
$ seq -f "%g%" 1
seq: %: invalid conversion specification
After this commit:
$ seq -f "%" 1
seq: format '%' ends in %
$ seq -f "%g%" 1
seq: format '%g%' has too many % directives
This matches the behavior of GNU `seq`.
Currently fails with:
```

- improve move-to-self detection, so this errors without data loss:
```diff
mkdir mydir
mv mydir mydir/subdir
-mv: No such file or directory (os error 2)
+mv: cannot move 'mydir' to a subdirectory of itself, 'mydir/subdir'
```
- align "cannot move source to a subdirectory of itself" and "same file"
errors more closely with coreutils:
```diff
mkdir mydir
mv mydir/ mydir/..
-mv: cannot move 'mydir/' to a subdirectory of itself, 'mydir/../mydir/'
+mv: 'mydir/' and 'mydir/../mydir' are the same file
```

* cut.pl: adjust to our messages as they are better
but we still have some differences on this test
* cut: add some missing line return when needed
* cut: add failing tests covered by cut.pl
* Remove dup test
* cut: add spell-checker:ignore line to test

Fix bug #6944
Rework the way batching is done with sort such that it doesn't open
more input files than necessary. Previously, the code would always
open one extra input file which causes problems in ulimit scenarios.
Add additional test case.
