Hmm. Looking at verify_headers(), I think it has another bug.
It wants to "return report(...)" as soon as it sees a problem, and stops
looking for other ones. But the new model for reporting errors is that
report() might ignore a problem if configured to do so.
So I think if you were to ignore NUL_IN_HEADER, then a commit with
NUL_IN_HEADER could still pass fsck, even though it should trigger
UNTERMINATED_HEADER.
