commit 08cc0ef8320e614c1a33ea5e70bef4f5809981f2
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Wed Jul 6 13:01:08 2016 -0400

    Capture the LOG_ERR messages in our tests that had logged errors.
    
    (It's confusing for the test to write an expected error to stdout,
    and then tell the user "OK".)
