The cause: core.worktree gets set to point to the trash directory. This results from a facet of the test I was not paying attention to --- the trash directory is a git repository itself, which poisons git with some extra information it hadn’t learned to forget yet. The third and fourth tests below fail in master for this reason. The first test passes everywhere; it is just checking basic behavior. The second test passes in master and fails in nd/setup without the git.c hunk of your patch. It is a more targeted test, meant to check only for the problem your patch solves. Of course, with your patch applied, all four tests pass. Thanks.
