    > How should it be wrapped semantically?

This is a psychological case to demonstrate how semantic wrapping does not by itself solve the "hard vs soft" wrapping question. If the answer is that the word should remain as a single word, then you are using soft wraps (or no wraps at all). If the answer is that the word should be split into 80 character chunks, then you're using hard wraps.
