Commenter is not clear what the current text means -

* Section 4.1.2 "If the request contains a Cache-Control: no-transform
directive proxies must forward the request unaltered to the server,
other than to comply with transparent HTTP behaviour and as noted
below." I'm not sure what this sentence means.

I've change the comment from substantive to editorial, since clarity is 
an editorial issue.

The current text makes reference to section 4.1.6 (of the CT Doc)  which 
is about adding via headers and the like.

The text would probably read better if it made reference to sections 
13.5.2 and 14.9.5 of HTTP 
http://tools.ietf.org/html/rfc2616#section-13.5.2 and 
http://tools.ietf.org/html/rfc2616#section-14.9.5 respectively.

Along the lines of "If the request contains a Cache-Control: 
no-transform directive proxies must follow HTTP sections 14.9.5 and 
13.5.2." Which is no more than saying that HTTP proxies should follow 
HTTP - but which in turn might be confusing since 13.5.2 doesn't refer 
exclusively to the treatment of no-transform, and one might wonder why 
we don't reference it in other circumstances too.

[fwiw the reason originally was to point out specifically that 
no-transform can occur in requests as well as responses]
