How to move redmine to a sub-URI with nginx as a proxy

Question

I want to put redmine (listening on localhost:3000 standalone passenger) behind nginx, serving from http://domain.com/redmine with this simple nginx config:

server {
    location /redmine/ {                                                                                                                                                         
        proxy_pass      http://domain.com:3000/;
    }
}

I rewrote redmine's config/environments.rb based on the instructions from this HOWTO, and redmine properly rewrites static asset URLs, but controller URLS are not rewritten, for ex. settings point to http://domain.com/settings instead of http://domain.com/redmine/settings.

How can I properly configure redmine to run behind nginx?

This is a pretty complicated thing to do. You wouldn't think so but it is. Every single redmine version that comes out has a different set of correct and incorrect ways of accomplishing this. For example, I have a working configuration with (nginx-1.4.1, unicorn, redmine-2.2.1) but now that I'm using (nginx-1.4.2, unicorn, redmine-2.3.3) that doesn't seem to work anymore.
