Actually, this isn't true. Any attempt to access internal location results 
in 404 response.

You can verify this with very simple configuration:

server {
    listen 8000;
    location / { return 500; }
    location /x { internal; return 500; }
}

Accessing /x will result in 404 response. This is a bug and it's somewhere 
on my TODO list.
