I find that the above argues that this patch is a bad idea. The change sweeps the problem under the rug, killing the canary in the mine, instead of motivating you to figure out why it is happening to you. Of course, scripts could choose to ignore errors from "git clean" it runs. At that point, the "sweeping under the rug" ugliness is not in Git, which is better ;-). -- 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
