That can help by teaching people how GIT_DIR behaves in general. But the warning and hint will be small consolation to somebody who runs "GIT_DIR=foo.git git clean -f" and sees it for the first time. If you want to argue that people would see the warning in earlier runs of git, I can kind of buy that. Although the incident that triggered this discussion probably wouldn't have (I would usually start a git-clean session with "git clean" without "-f" or "git status", either of which would have done equally well as this warning to notify the user what was going on). Like I said earlier, though, I'm not really sure this is the direction we want to go. This series is more about seeing what the fallouts are. I probably shouldn't have included this middle patch at all, because the interesting thing is what happens when we do turn it off. -Peff -- 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
