Sorry for talking to myself, but I'm not convinced 1 is any better than auto. Despite my protestations below, it could be that we *do* want to respect widows and orphans at some time in the future, in some situations. I like that 'auto' has the implication that the user-agent will decide.

Someone please convince me one way or the other!
