I have some Python applications running under my ngx_http_wsgi_module.

For these application, I set the Nginx prefix command line option to the
application working directory.

- From Nginx configuration I use the wsgi_var directive to set the path to
application configuration file, and currently I have to do something like:

   set $app_path /path/to/application
   ...

   wsgi_var app_conf_path $app_path/settings.yml


With the prefix variable, I can avoid having to define an additional
variable:

   wsgi_var app_conf_path $prefix/settings.yml


I don't know if there are some other possible use cases.

Usually in Nginx there is no need for the "prefix" variable, since most
of the paths in directives are resolved against the prefix path.
