Try running "git config --unset core.worktree" in the .git dir.

It looks like "git init" will write a core.worktree entry in this case, even though it isn't technically needed. I think it is due to these lines in builtin/init-db.c:

                if (!starts_with(git_dir, work_tree) ||
                    strcmp(git_dir + strlen(work_tree), "/.git")) {
                        git_config_set("core.worktree", work_tree);
                }

The check returns a false positive for the root directory because we only have one slash (i.e., appending "/.git" to our worktree would be "//.git" in this case).
