State-Changed-Why:

This is intentional.  The presumption is that such
encoded slashes are being used as a form of attack, to
access restricted portions of the system that would
automatically be denied if the unencoded slash were
used.  The current version of the CGI spec (under
development at <http://Web.Golux.Com/coar/cgi/>) says
that the server can impose whatever restrictions it
likes upon PATH_INFO.  It's unclear whether rejecting
the request (as Apache currently does) is preferable to
invoking the script with PATH_INFO reduced to an empty
string.  PATH_TRANSLATED is closely related.
