Yes, but have a look at ap_getline in protocol.c which was used before instead
of ap_proxygetline. It does exactly the same thing regarding the brigade.
So his solution is not less efficient than the old one. Of course it can be 
discussed
whether the old one was efficient enough :-).
I guess we can create a brigade for this purpose at the beginning of
ap_proxy_http_process_response pass it to ap_proxygetline and do a 
apr_brigade_cleanup each time
after we have called ap_proxygetline. But in this case we can also use
ap_rgetline directly in ap_proxy_http_process_response as there is not much 
left of
ap_proxygetline in this case.
The other aspect of this patch is the matter of code duplication. The question 
is
whether it is good to nearly duplicate the code of ap_getline and thus have to 
manage
it twice in different locations.
