Wouldn't the issue you and Jonathan are talking about disappear with:

    diff --git a/t/t0000-basic.sh b/t/t0000-basic.sh
    index c2f5f8d..69e219b 100755

Note the change to passing-todo, that uses the same setup style.

With that the output of:

    $ rm -rfv trash*; ./t0000-basic.sh --debug; cat trash\
directory.t0000-basic/{passing-todo,failing-cleanup}/*.sh

Is now (cut):

    # Point to the t/test-lib.sh, which isn't in ../ as usual
    TEST_DIRECTORY="/home/avar/g/git/t"
    . "$TEST_DIRECTORY"/test-lib.sh

    test_expect_failure 'pretend we have fixed a known breakage' '
        :
    '

    test_done
    #!/bin/sh

    test_description='Failing tests with cleanup commands'

    # Point to the t/test-lib.sh, which isn't in ../ as usual
    TEST_DIRECTORY="/home/avar/g/git/t"
    . "$TEST_DIRECTORY"/test-lib.sh

Instead of previously being:

    # Point to the t/test-lib.sh, which isn't in ../ as usual
    TEST_DIRECTORY="/home/avar/g/git/t"
    . "/home/avar/g/git/t"/test-lib.sh

    test_expect_failure 'pretend we have fixed a known breakage' '
        :
    '

    test_done
    #!/bin/sh

    test_description='Failing tests with cleanup commands'

    # Point to the t/test-lib.sh, which isn't in ../ as usual
    TEST_DIRECTORY="/home/avar/g/git/t"
    . "/home/avar/g/git/t"/test-lib.sh

I.e. before the TEST_DIRECTORY was always expanded.
