Log message:
Add check for opt crash.
This idiom is becoming more and more prevalent. While it works, its also
doubling the runtime of each test its used in. I'm wondering if we could
invest in a "notgrep" script (since we're invoking "not" anyway) that
would fail on empty input. Is this sufficient to avoid having to do
things twice?
It won't work. The command can crash after producing some output, but
still not producing a line being grepped for.
