ap_run_sub_req and content length

[Aryeh Katz]

I wrote here earlier about using ap_run_sub_req to send a response to a 
client, and I receieved excellent advice, thank you.
There is one thing I was wondering.
I see that the Encoding is chunked.
I would prefer to set the Content-Length to the correct length, rather than use 
chunked encoding.
How can I do this (other than reading the brigades, then running 
ap_set_content)?
