description:
if_ade doesn't build, suggesting nobody has tried to do anything
else than rototill it for the past n+1 years. The comments at the
top note a number of clauses after which it can be removed. I'm
sure that in the past 10+ years those have either been met or become
irrelevant, so remove this.
