Subject: [PATCH 01/14] test-lib: add test_dir_is_empty()
Message-ID: <539DD068.6020301@web.de>
In-Reply-To: <539DD029.4030506@web.de>

For the upcoming submodule test framework we often need to assert that an
empty directory exists in the work tree. Add the test_dir_is_empty()
function which asserts that the given argument is an empty directory.
