setup-project.py: the clone path <into>/<Project> is refused in step (3), before anything is created, when anything at all stands there, naming the path and telling a rehearsal's leftover clone apart as one to move or delete, and the plan names the clone path before the yes, so rehearsing and then running for real in the same folder - README's own order - no longer creates three repositories and then refuses with a hand clone that fails on the same directory (#498) - #509
