OK, thanks for clarifying that. My comments in the last message can
therefore be totally ignored. Mind you, I still don't understand how
the simplify way patch can work correctly. Perhaps it's time I
actually tried it out.

The change that v3 introduced could be retro-fitted to trunk as it's
essentially independent of the bogus node removal.
