Nginx 0.8.36 and content cached with 0 bytes size

Hi,
Maxim D. pointed me to these patches for the problem I have with
content
cached with 0 bytes size:

http://nginx.org/pipermail/nginx-devel/2010-January/000101.html
http://nginx.org/pipermail/nginx-devel/2010-January/000102.html

Could I apply them in 0.8.36? Why these patches aren’t integrated in
source tree?

Thanks,
d.
