I haven't been able to reproduce this locally either. If I just use a 
repo after 'git init', the return value of vc-git--run-command-string 
(inside project--vc-list-files) is an empty string, not nil.

Could this be that the repo in the test isn't actually initialized? Or 
maybe there's something different in the test environment. My Git 
version is 2.37.2.
