Why do you use two different errors?

Don't they have different outputs?

Hm, at least on my machine with Arch Linux GNU mv shows the same error in both cases (see the ticket). I could imagine it depends on the underlying system, so we can leave it.

@cakebaker does this PR really achieve the goal of the issue then? Which mv are we trying to emulate?

Yes, the goal is to get better error messages and your PR achieves it. We try to be compatible with the latest version of mv. In this case it is not possible, though, as the behavior depends on the underlying system. This is why there is no test for it in https://github.com/coreutils/coreutils/blob/master/tests/mv/trailing-slash.sh and the authors write in a comment:
We would like the erroneous-looking "mv any non-dir/" to fail,
but with the current implementation, it depends on how the
underlying rename syscall handles the trailing slash.

I guess you have seen the error from the CI that there is no as_bytes function under Windows?

The pipeline wouldn't run until someone from this project had approved it. Thanks for pointing out that they are running now.

@cakebaker can I run the workflows locally? They won't run until they're approved:

@mickvangelderen the approval is no longer needed and the workflows should run automatically in the future.

Fixes #5463
The implementation of mv seems a bit messy, at least to a first time reader. My changes also feel a bit "band-aided" in. Glad we have a bunch of tests but the many repeated calls to
is_dirandsymlink_metadataand hard to understand flow may need to be addressed.
