dispatch: error out on invalid -R path even if optionalrepo (issue4805) (BC) Before this patch, repo could be set to None for wrong -R. It's okay for commands that can reject repo=None, but the command server have a problem because: - it accepts repo=None for "unbound" mode - and it reenters dispatch() where repo object is created for cwd by default Test outputs are changed because the error is detected earlier. I think new message is better than ".hg not found".
