Note that "nice -20" is short for "nice -n 20", that means more than the max
niceness, or in other words the min priority.

(That is, assuming the process starts at nice 0; since the argument to nice
is an increment, it the process starts with a niceness <-1, it will not
reach +19 by adding 20.)

renice, on the other hand, accepts a bare priority argument, and therefore
"renice -19" really means lowering the niceness. Obviously the first
developers who implemented this wanted to have a good laugh.
