That works for me.  I don't mind it saying LINE 1: in the one-line case.

Well, what I'm imagining is that you sprintf("LINE %d") and then strlen
that in the process of constructing the first line, and later add that
length to the offset you need in the second line.

Tatsuo's complaints about characters that span more than one position
are a much nastier problem, in any case :-(.  Can we cope?
