To me, "unset" and "not set" are not the same thing (sort of like how > "untie" and "not tied" are also not the same).
Well, yes, except that "unset" and "not set" also *ARE* the same thing, sort of like how "untied" and "not tied" are also the same thing! (Since untied is the past participle of untie -- but unset is the past participle of unset, hence the ambiguity!) Cheers!
