By default, it shoots for a valid but relatively snappy response at the cost of conciseness. But can you can add --minimal if you really want it to work harder at producing tighter output. I say that not to propose that you make this behavior optional, but merely to point out another (practically ancient) case of a diff algorithm's default behavior favoring performance over conciseness.
