Thanks for pointing out!
I'll try to fix this issue...

Is there are more elegant solution to achieve desired functionality?
Without patching nginx sources by adding new NGX_HTTP_*_BUFFERED constant?
There is only limited number of slots available, and if not with sub
filter, it may cause incompatibility with
other external modules, if they happens to use the same bit.
