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?</pre>

It won't work. The command can crash after producing some output, but
still not producing a line being grepped for.<br>
