So I should have said something like the following instead:
These scratch areas for sub-tests should be under the t0000 trash
directory, but because TEST_OUTPUT_DIRECTORY defaults to
TEST_DIRECTORY which is exported to help sub-tests find test-lib.sh,
the sub-test trash directories are created under the toplevel t/
directory instead. Because some of the sub-tests simulate failures,
their trash directories are kept around.
Fix it by explicitly setting TEST_OUTPUT_DIRECTORY appropriately
for sub-tests.
Thanks for catching it.
