This is fixed in the follow-up commit. Rather than making such a fundamental change and having to deal with the fallout by introducing complexity to handle various special-cases which pop up now and in the future, I wonder if it makes more sense to instead just update documentation to tell hook authors to read explicitly from the console rather than expecting stdin to be available (since stdin may already be consumed for other purposes when dealing with hooks or commands which invoke the hooks).
