I though RobH was asking about CGI scripts in the context of server-side
includes, which this does not mention.

And it doesn't say we couldn't....

In fact, treating null path segments specially would be quite legitimate.
httpd already imposes some semantics on the URL path, part of which
is sent to the CGI script as PATH_INFO. Consider: we parse '/../' in both the
document URI part and the PATH_INFO, removing it and the previous path
segment. Similarly, httpd ignores '//' in the doucment URI part, so maybe it
should also in the PATH_INFO ?  8-)
