No, it does not.  That is the entire point.  RMS and others are
telling this was a bug that was fixed in 21.1.  This example is from
20.7:

x
#("(defun fo" 0 1 nil 1 6 (face font-lock-keyword-face) 6 7 nil 7 9 (face 
font-lock-function-name-face))

(format "%s" x)
"(defun fo"

(format "%S" x)
"#(\"(defun fo\" 0 1 nil 1 6 (face font-lock-keyword-face) 6 7 nil 7 9 (face 
font-lock-function-name-face))"

I depended on the 20.7 behavior.
