Either way is grammatically correct.  Really, this is a philosophical
question.  Can two empty strings have different identities?  Or is
there only one empty string in the universe?

(eq "" "") => t
(eq "" (string)) => t
(eq "" (make-string 0 ?a)) => t
(eq "" (substring "a" 1)) => t

It would appear Elisp is squarely in the "there is one empty string"
camp, so "the empty string" would be more correct.
