I don't think I buy the "shirttails as underwear" theory. There's ample evidence for 15th century underwear, and I can't see why it would suddenly go away. I think they are long so that they are less likely to ride up as you move. I have one shirt that is only about hip length, and as the day goes on it tends to crawl up inside my doublet. When your pants are pointed to your doublet, there's no easy way to get the shirt back down. If the shirt is long enough to tuck it down into the pants, this problem is eliminated.
