Precisely.  It does not say to unquote a quoted-string because that's
not how cookies work.  The role of the quote character is cookies is
identical to the role of the "!" character.  That is, neither play a
special role in the protocol.  Any representations by the contrary by
2109 or any other document are fiction and have only caused pain and
misery in the world.
