Adding $request_path Variable

[adamchal]

It would be very nice if someone would add the following variable to
Nginx:

$request_path

Right now, we have $request_uri which includes the query string of the
original request.  We also have the $uri which is the path portion of
the $request_uri, but it is the path AFTER the rewrites.  What would be
very useful is the $request_path, which would be the original path
portion of the $request_uri.

I use a very efficient TSV access log that can be imported and parsed
VERY quickly by our analytics software.  The problem with logging the
$uri is that for requests that generate a 500 error, we lose the
original request path since the error_page directed rewrites the $uri.

Thoughts?
