Unlike the opt-prefix-length I removed in 1/3, the length of the line-prefix will never change during the lifetime of a single diff_options struct, so it might turn out that repeated strlen() on it for each and every line output is wasteful.

Other than that, I didn't spot anything immediately questionable.
