As somebody in the newspaper business, I think it's very unreasonable. Editors also put a lot of effort into choosing good font faces, weights and sizes, but you're insane if you think you own the copyright on mixing 11.3 pt Minion Pro-Demi with 12 pt Balboa-Bold. The fact of the matter is, it may in fact be an excellent and highly creative look, but it's still unreasonable to copyright something that simple.

Headlines are even worse, because they're the piece's name. If headlines fall under copyright, it becomes potentially illegal to talk about a news article. That makes copyrighting a standard font library look downright logical.
