And I goofed: Transfer-Encoding is the stuff that says
"chunked". I was thinking of Content-Encoding. But the
section I refered to also says:
"If a Content-Length header field (section 14.13) is present, its
decimal value in OCTETs represents both the entity-length and the
transfer-length. The Content-Length header field MUST NOT be sent
if these two lengths are different"
[And a little further down, it mentions "that the
recipient can arse it". I'm not sure quite what
to make of that. :-)]

Come to think about it, I've written some output handlers
to convert utf-8 to utf-16 or -32, which uses either
'Content-Length' or 'Transfer-Encoding: chunked' depending
on the size of the output. Perhaps I should change that to
always 'chunked'...
