GNU testsuite comparison:

Skip an intermittent issue tests/date/resolution (fails in this run but passes in the 'main' branch)
Skipping an intermittent issue tests/cut/bounded-memory (passes in this run but fails in the 'main' branch)
Skipping an intermittent issue tests/tail/tail-n0f (passes in this run but fails in the 'main' branch)
Congrats! The gnu test tests/cp/link-heap is now passing!

Where is the place more-error-is-directory cannot be replaced by os error? (Removing it at another PR is fine).

[Devel08]

File::open() doesn't throw an error when a file is a directory, thus we have to check that manually

[oech3]

EISDIR (or EPERM) is returned when read was called for directory. So the arm

coreutils/src/uu/more/src/more.rs

Lines 42 to 51 in 92cbd2f

	Self::IsDirectory(path) => {
	write!(
	f,
	"{}",
	translate!(
	"more-error-is-directory",
	"path" => path.quote()
	)
	)
	}

can be removed on many unix.

[Devel08]

yeah it's returned on read, but the message will look something like "more: Is a directory", the path will be missing, if we rely on the message that read returns, should we let read's message or the custom locale?

[oech3]

I'll fix this at different PR using format! or something else.
