First, my patch is also an improvement here since it allows showing tags (previously, it showed only stage). The idea for showing stage before tag is that the cost of deletion is greater than the cost of insertion, which corresponds to the hypothesis that it's more common to miss one character when typing than typing too many. That's probably subjective, but I think it makes sense. -- Matthieu Moy http://www-verimag.imag.fr/~moy/ -- 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
