Yes, it is. I've actually started with the preprocessed input initially, but it
was so big (~90kLoC) that delta didn't make much progress with it after running
for ~2 days, which is why I finally didn't use it. And preprocessing the
current test case still results in a ~55kLoC file, so I've had to compress it
to attach it here.

Sure, done now.

Thanks again for looking at this!
