  um, oops. I actually never got to know these by heart since I learnt
to expliciply group the expressions early on. I guess my only excuse is
that I've stumbled at 0bdf93cbf earlier and understood it the _wrong_

  I still think my change improves the code readibility so it could be
kept, but I'm fairly neutral on this.
