The heuristic won't _really_ see wide use until it is in a released version of git, as much as we would like it to be otherwise. So I am anticipating a possible conversation where somebody reports that the new output looks bad, and it would be nice to say "try it with this flag (or environment variable, or whatever) and see if that looks better". And then based on that conversation we can decide what the right next is (a real user-visible flag, or reversion, or deciding the user's case isn't worth it). Or maybe if we're lucky that conversation never happens. The "whatever" in the instructions can obviously be "build with this patch" or "try with an older version of git", but we're a lot more likely to get a good response if it's easy for the user to do. -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
