Summary `git -C (folder path) diff-files --name-only` output is not correct
Steps to Reproduce 1. Apply change to a clean git repository. Go to another folder (not within this repository) and apply the command `git -C repo-path diff-files --name-only` The above command lists dirty files in that repository. 2. Now undo your changes on the repository 3. Issue the same command. It still lists the file. More Information `git -C repo-path diff` command doesn't seem to have this problem. System Information Arch Linux 5.0.7-arch1-1-ARCH git version 2.21.0
