Thanks for the patch, but no.
In no particular order:

- The wiki is not something official, it's user-contributed 
  content with mostly arbitrary quality, use it with caution.  
  Official documentation is available at nginx.org/docs/.

- The fastcgi_params file lacks SCRIPT_FILENAME intentionally.  If 
  you are using PHP and want to set it to 
  $document_root$fastcgi_script_name (which is not always the case), 
  you can use fastcgi.conf file.  In contrast, fastcgi_params can
  be used when you want to set SCRIPT_FILENAME to something 
  different, for example, to use a specific directory (see 
  nginx.conf for an example, 
  http://hg.nginx.org/nginx/file/tip/conf/nginx.conf#l63).

- PATH_INFO is, similarly, to be set explicitly when you've 
  configured nginx to provide one, see 
  http://nginx.org/r/fastcgi_split_path_info.

- PATH_TRANSLATED is implementation-defined, and nginx does not 
  try to define it.  If you want to use it, it is up to your 
  specific environment to set it to something.

Hope this helps.
