I think this change is OK. But I wonder whether we should encapsulate the logic into the "repo_config" function. It's a little cumbersome to check whether the "repo" exists. I also feel it's a bad idea to check in the "repo_config" function because in the most time, we run commands inside the repository. So, in my view, at current, this is enough. Thanks, Jialuo
