When using cprow, this should always be exact, right?

If we are not using cprow because there weren't enough empty rows, but
there are still some empty rows, it won't be exact, but it's likely not
far off for typical matrices.  It would be a shame, however, that we
could now compute a negative number of flops.  Should the check for
cprow store the number of zero rows?
