[Web-SIG] FYI: Changes to PEP 333 and wsgiref

I noticed today that the "URL Reconstruction" algorithm in the PEP (which I 
also copied into wsgiref) is incorrect.  HTTP_HOST (aka the 'Host:' header) 
can contain a port, if it's not the default port for the corresponding 
protocol.  So, SERVER_PORT should not be appended to it in that case.  I've 
fixed the PEP and wsgiref.  (The PEP update should be visible on python.org 
within an hour or two.)

In addition, I've also updated the PEP to make SERVER_PROTOCOL a required 
environ variable.  It's impossible to comply with the HTTP RFC's if you 
don't know what HTTP version the client is using.  (Despite its name, 
SERVER_PROTOCOL is actually the *client* protocol: "the name and revision 
of the information protocol with which the request arrived", according to 
the CGI spec.)

Finally, while making the updates, I also added a notation to the effect 
that 'wsgi.errors' is intended to be a "text mode" file.  This was always 
the intent, but the fact wasn't documented.
