Summary: cgi module. FieldStorage class returns keys blank fields.

Details: In module cgi.py

The FieldStorage class returns keys for blank values even though the
keep_blank_values property is set to 0

The problem lies in the parse_qsl method.
The second last line of the function
  r.append((name, value))
should read
  if (len(value) or keep_blank_values):
      r.append((name, value))  

I hope this can be corrected.

Thanks

Comment:
I don't see why this is necessary.  The r.append()
call is inside an if block whose condition is
'if len(nv[1]) or keep_blank_values'.  nv[1] then has + replaced with space
characters and is run through
urllib.unquote().  I'm unable to see how a non-empty string could result in
an empty string after urllib.unquote, and in fact
cgi.parse_qsl('abc=&foo=bar') returns [('foo', 'bar')].  Can you provide a
test case?

If a test case demonstrating the problem doesn't appear, this bug should be
marked as 'Not a bug' and cgi.py left alone.

Assigned to Andrew since he knows more about CGI stuff than I ever expect
to.
