Good points. And I'm not really sure if I'm gonna need it. Or even want it. But then I can imagine situations, call them corner cases, in which that would be desirable. As always, desirability is in the eye of the beholder, but the situations I'm referring to are those in which on line-at-a-time could become clumsy if you want to take into account human readability. Whatever, I'd still be interested in the feasability of the thing, and about how one would go to accomplish it.
