numerology_1.out and float8-small-is-zero_1.out differ from their base files only in showing plain zero rather than minus zero for some results. I believe that in the wake of commit 6eb3eb577, we will print minus zero as such on all IEEE-float platforms (and non-IEEE floats are going to cause many more regression diffs than this, anyway). Hence we should be able to remove these and eliminate a bit of maintenance pain. Let's see if the buildfarm agrees.
