Hmm, that is a list in there, not a two-element tuple:

scheme@(guile-user)> (car '(("A" "B")))
$1 = ("A" "B")
scheme@(guile-user)> (car (car '(("A" "B"))))
$3 = "A"
scheme@(guile-user)> (cdr (car '(("A" "B"))))
$2 = ("B")  <---- should be "B" without the parens for tuples

So I suggest either fix the example to be a pair ("sftp" . 
"/usr/libexec/sftp-server") or fix the docs.
