Hm, I think I even had caught that issue on the mailing list previously.

In that case though, it seems even the existing code is insufficient. Instead
of testing whether the operator with strcmp against "=" and "<>" it should
perhaps be looking for an operator class and the strategy number for the
operator and its negator.
