What I was puzzled with was what it has to do > with "if blue is the sky" (which is a bad analogy for "if (0 < len)" > anyway)? Yoda speaks in reverse "Stopped they must be; on this all depends". "if (0 < len)" says "if zero is less than len", which is in reverse, as reverse as "if 1.50 is taller than you". It's all reversed: "if you are taller than 1.50", "if len is greater than zero", "They must be stopped; all depends on this". I don't understand what is not clear. -- Felipe Contreras -- 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
