+Either way is grammatically correct. Really, this is a philosophical\r
+question. Can two empty strings have different identities? Or is\r
+there only one empty string in the universe?\r
+\r
+(eq "" "") => t\r
+(eq "" (string)) => t\r
+(eq "" (make-string 0 ?a)) => t\r
+(eq "" (substring "a" 1)) => t\r
+\r
+It would appear Elisp is squarely in the "there is one empty string"\r
+camp, so "the empty string" would be more correct.\r
