this can not be squashed because i would like:

• one commit to enable new clippy warnings
• one or several commits to fix them please rewrite the stack (git rebase -i origin/main is your friend)

I pushed that fix: https://github.com/uutils/coreutils/pull/6505/commits/cac18fb7794c5c31a6b29e671ba239330d7ba381
