Well the spec does say that 
"if the line begins with the termination octet and if
 octets other than CRLF follow, the first octet of the line 
 is stripped away by the client"

Though I do admit I can see no other case than that of a doubled ..
where it might happen seeing as 
"If any line of the multi-line response begins with the termination 
octet, the line is "byte-stuffed" [by the server] by pre-pending the 
termination octet to that line of the response."
So the second should also be ok.
