Can & should just be "git init", see f0d4d398e28 (test-lib: split up and
deprecate test_create_repo(), 2021-05-10).

The "-p" here isn't needed, you're not creating recursive directories.

Can't this just use test_stdout_line_count? Except...

This test seems a bit odd, here we're just checking that we've created
scratch files for the internal use of our test, why is it important that
we have an "out" file, when the only reason we have it is because we
needed it for checking the "ls-files" line count above?

ditto.
