A sound but incomplete reasoner can return 3 different results -
"yes", "no" and "don't know". We clearly need to distinguish failure
in the sense that a yes/no answer was returned but was incorrect from
the case where a don't-know answer is returned. Reporting something
like "incomplete" for the don't-know case seems reasonable and, as
was pointed out by Jeremy, is not pejorative.

I don't believe that it is either desirable or sensible for the
results to distinguish good/bad incompleteness. Bad incompleteness is
unsoundness and can simply be reported as "fail".
