It would be 2 here, and would quite possibly leave headers unconsumed,
which is in error. The current behaviour is definitely 
preferred for this case (signalling an error) but my feeling is that 
this behaviour, while quite acceptable in this example, is not 
the best for all cases (news.ycombinator.com for example). 

In the same vein the approach I've suggested is definitely not 
the best for all cases, merely a method to workaround 
servers that do not honour RFC 2616[1]. 

Cheers,
Sean.


[1] Granted this is done by ascribing semantics to single CR's and LF's
    in an essentially ad hoc manner.
