I think the change is fine, please install it, and thanks.  Let's hope
it doesn't break on Emacs 26.3, 27 and 28 

(f you could test, it would be great, if not it's OK.  It'd involve
making a GitHub fork and using the GitHub actions scripts)

A safer, but slightly slower route:

   (should (zerop (shell-command "git init")))

Some tests known to need project-files already do this.

But why does it pass on Emacs 29?? Maybe project-files simply doesn't
error there?
