Exit code = 1 for `--csv skip-trivial-records` and CSV file's last record is blank

[garyaderhold]

It makes sense to receive an exit code of 1 if the CSV contains a blank record and "skip-trivial-records" is not specified. But, if I specify "skip-trivial-records" and the file does indeed have trivial records shouldn't the exit code = 0?

That, or create another exit code that's for maybe warnings like this.
