[issue9019] wsgiref.headers.Header() does not update headers list it was created with.

[Marcel Hellkamp]

New submission from Marcel Hellkamp :

The current (3.x) implementation of wsgiref.headers.Headers() does not match 
the documentation.

Documented behaviour:
"Any changes made to the new Headers object will directly update the headers 
list it was created with." (/Doc/library/wsgiref.rst)

Actual behaviour:
The initial headers list is not updated.

The error was introduced with revision 68205. See 
http://svn.python.org/view/python/branches/py3k/Lib/wsgiref/headers.py?view=diff&r1=68204&r2=68205

Revision 68204::
>>> from wsgiref.headers import Headers
>>> l = []
>>> h = Headers(l)
>>> h.add_header('Test','Test')
>>> l
[('Test', 'Test')]

Revision 68205::
>>> from wsgiref.headers import Headers
>>> l = []
>>> h = Headers(l)
>>> h.add_header('Test','Test')
>>> l
[]
