The previous code would have written an empty file to --iidfile in this case, changing that to an error would be an externally visible change.

In fact, looking at the code now, none of the changes in this file are actually needed, they're just a refactor due to me originally printing the digest here (and hence pulling the digest out for printing/writing to the --iidfile).
