I think the idea was that *any* path under $(git rev-parse --show-toplevel) would not be a valid GIT_DIR, unless its last path component is ".git". Alas, I don't think that would work smoothly. - Some people may already be using GIT_DIR=$HOME/dotfiles.git to track some files with a toplevel of $HOME. That is error-prone and it would be cleaner to either use plain .git or keep the $GIT_DIR outside the worktree (for example by tucking dotfiles into a separate $HOME/dotfiles dir), true, but producing a noisy warning with no way out would not serve these people well. - There is no outside-the-worktree location when GIT_WORK_TREE=/. So your suggestion of at least noticing when "git checkout" wants to write files that overlap with the GIT_DIR seems simpler. -- 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
