This should fix the diff tests failure on s360x. It's a serious problem and I plan to do something to prevent it from happening again.
The second patch should bring '-U' (no argument) back. Whether it makes sense to accept this behavior is not part of this conversion. We can deal with that later. The third patch also brings back a corner case behavior of --inter-hunk-context and as a result strengthens OPT_INTEGER() error handling a bit.
