Also, the entire semantics are a bit strange. When I'm deciding whether I want text to line wrap, I don't really think about whether the whitespace should wrap. Yes, whitespace is somewhat relevant to the topic, since that's one option of where to break lines in order to line wrap, but I still think of it as the entire text that is line wrapping.

Oh, and don't forget that there is in fact a word-wrap property, which is a much better name for the previous behavior, but in fact only customizes how the line-breaking algorithm determines which words can be broken apart.
