It can't: "This is the original URL-encoded value derived from the 
request URI. If the server cannot provide this value, it must omit it 
from the environ". A CGI gateway doesn't have access to the original 
URL-encoded value.

The alternative to duplication would be to allow a gateway to try to 
'reconstruct' `path_info` from CGI `PATH_INFO`.

If this is done there really needs to be a flag somewhere to say that it 
has been done, ie. that `/` and non-ASCII characters in the path are 
unreliable. Otherwise we're just going to end up in the same sorry 
situation we have today where all sorts of different encodings and 
corruptions lurk inside PATH_INFO and apps simply cannot rely on it.

Please don't have a field with encoded semantics that re-uses the name 
of a field that has always had decoded semantics.
