(minor; ignore if desired) The above could be simplified to:

    rm -fr foo bar &&
    git init foo &&
    mkdir bar &&
    >bar/goodbye.people &&

> +       git clean -f -d &&

Here and elsewhere, you could instead use test_path_is_file() and
test_path_is_missing(), respectively.

Simplified:

    rm -fr foo bar &&
    git init --bare foo &&
    mkdir bar &&
    >bar/goodbye.people &&

Alternative, here and elsewhere: test_path_is_dir()

Although in the latest POSIX, -A may not be portable.

Alternative: test_dir_is_empty()
