I thought about it for a minute when writing the patch I posted, but
wasn't really sure what the test case would look like.  The only
external proof that the case worked correctly, AFAICS, is the DEBUG1
message that's written to the log.  How do we add a test case with
that?  I know you mentioned an idea before to check/grep the log for
such cases.  Is that how?
