But if someone wants to reassemble individual sentences into paragraphs, as anyone knows who has tried to reassemble lines into paragraphs (as with an e-mail in its delivered form), it's nearly impossible to get right. Is it? I haven't seen LaTeX do it wrong yet. Of course, I use actual formatting code to specify format -- what I'd give to someone else is the rendered document, not the LaTeX source.
