Is there any use case where HEAD...HEAD (or "..." alone) is actually useful? I have re-read the git-diff man page and I don't think it explains "git diff foo ... bar" syntax (from a user's point of view, not a git guru's). We could improve the documentation if "git diff foo ... bar" is useful, or reject it with an error to avoid confusion. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
