Right, the hint makes no sense here. I'll look into adjusting the output to be appropriate. As a minor note: I believe your "git add repo/" comments above describe what should be and not what currently is. The trailing slash results in adding the content from the specified repository to the current repository rather than registering the repository as a submodule: $ git --version git version 2.21.0 $ git init $ git init a $ git -C a commit --allow-empty -mmsg $ touch a/f $ git add a/ $ git status -s A a/f This behavior (and fixing it) was discussed at https://public-inbox.org/git/20180618111919.GA10085@xxxxxxxxxxxxxxx
