It should defently be optional, and at least make differences between HTTP
headers that are added by Nginx and HTTP headers that are sent by the
client... seems like a good idea to me, doesn't it?

It makes things cleaner and allows to avoid injections of some unexpected
headers, like X-Real-IP, which might be used by complicated application by
some side effect.

P.S. I'm testing an updated patch, I think to send it soon.
