Documenting every function's behavior completely, in that function's doc = string=20 or manual section, would waste not only our time, but also time spent by = users=20 reading the documentation. Nobody does that, for any nontrivial GNU progr= am I'm=20 aware of. Common sense should prevail, and "document every bit of behavio= r"=20 absolutism would cause more trouble than it'd cure. Thank goodness we don= 't do=20 that, and have never done that.
