You are taking this out of context. It is not the case that you would 
parse through the message replaceing all instances of CRLF WSP with LWS.

The BNF specifies that message-header ends with a CRLF. What follows 
that is one of two things - either another CRLF, marking the end of the 
headers, or another message header, which never begins with LWS. Thus, 
if a CRLF is followed by something OTHER than WSP, the next construction 
cannot be LWS.
