I've encountered the folks who think that no. 2 is the only way to go, but, as Jon Boy says, it is merely a matter of style.

Many times it meant the difference between ambiguity and coherency, especially when you have lists of things that have combinations in them, such as ".., and peanut butter and jelly."
