Your interpretation is absolutely correct.  The attached patch should
take care of the issue.  Could you give it a try?

Well done.  This is a spurious failure that shouldn't interfere with
our test results.

This is not possible; the '*.tap' tests in the Automake testsuite
use the TAP protocol, and that mandates which output lines must be
interpreted as declaration of test results.  I think the workaround
implemented in the attached patch is the simplest and best fix.

Thanks,
