Does a previous test not delete 'repo' when necessary?

Or, do previous tests re-use 'repo' and now we are in a region
where we can safely clear that directory? Should we use a
different name?

This section is demonstrating the bug. Perhaps we should have
comments indicating that this is not desired behavior, but is
being demonstrated so the bug can be fixed by a later change?
