The responses:

Unanimous vote that negative checks are bad.  I really do want to check for
the absence of the word "OK" rather than the presense of a negative keyword.
I would have to be confident that I have all of the negative status indicators
correct.  So it just checks for the absence of the word OK with special cases
to remove hits on the table header, subject separators, etc.

Thanks to a lot of folks who, like me, are not on vacation this week!!!
