! 		4.3.    String
! 
! 		A string is in one of two forms: either literal or quoted
! 		string.  The literal form is the general form of string.  The
! 		quoted string form is an alternative that avoids the overhead of
! 		processing a literal at the cost of limitations of characters
! 		which may be used.
! 
! 		A literal is a sequence of zero or more octets (including CR and
! 		LF), prefix-quoted with an octet count in the form of an open
! 		brace ("{"), the number of octets, close brace ("}"), and CRLF.
! 		In the case of literals transmitted from server to client, the
! 		CRLF is immediately followed by the octet data.  In the case of
! 		literals transmitted from client to server, the client MUST wait
! 		to receive a command continuation request (described later in
! 		this document) before sending the octet data (and the remainder
! 		of the command).
! 
! 		A quoted string is a sequence of zero or more 7-bit characters,
! 		excluding CR and LF, with double quote (<">) characters at each
! 		end.
! 
! 		The empty string is represented as either "" (a quoted string
! 		with zero characters between double quotes) or as {0} followed
! 		by CRLF (a literal with an octet count of 0).
! 
! 		Note: Even if the octet count is 0, a client transmitting a
! 		literal MUST wait to receive a command continuation request.
