For that matter, running "git add ../../foo" from the top-level of the working tree falls into the same category. There are boundaries in both upward and downward directions that define the area you could add to the index. Now, I am not saying that "--ignore-errors" should _never_ mean to ignore errors of this kind. I was merely giving the historical background for the semantics you are observing. I personally think it might even be an improvement if you made the option to instruct the command to consistently ignore requests to add these paths outside the working tree boundary in any direction (not just the downwards boundary defined by the presense of a submodule, but the downwards boundary defined by the ".git" directory, and the upward boundary at the root of the working tree), and add only remaining valid paths to the index. I do not think it is the right thing to special case only the submodules, though. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
