IMHO this is so *obviously* confusing and misleading --- even though it 
is technically correct --- that whoever wrote it was either 
intentionally trying to be confusing or is unbelievably obtuse and/or 
out of touch with reality.

It is not (again IMHO) clear even to *very* careful readers.

To my mind this documentation fails even the fortune(350) test.
