[pan93412]

I will put the review to the translation PR later.

Thanks for taking the time to contribute to Git! Please be advised that the
Git community does not use github.com for their contributions. Instead, we use
a mailing list ([email protected]) for code submissions, code reviews, and
bug reports. Nevertheless, you can use GitGitGadget (https://gitgitgadget.github.io/)
to conveniently send your Pull Requests commits to our mailing list.

For a single-commit pull request, please leave the pull request description
empty: your commit message itself should describe your changes.

Please read the "guidelines for contributing" linked above!
