Hi, fairly new to Python, so not sure if this is something you want as a
behaviour or not:

urllib.response object when fetching an HTTP1.1 page does not
transparently handle "Transfer-Encoding": "chunked", and I think it should.

You can view source code for addinfourl, AbstractHTTPHandler and
HTTPHandler to verify this (sorry, I don't have line-numbers, I'm typing
this at home).

I would suggest extending addinfourl to "addinfourlchunked", for
example, to allow substitutes for, readlines() and readline()
to be specified during the construction of addinfourl.

This threw me initially, and seems like quite a glareing omission for

I'm sorry that I didn't notice this bug report in September!  The
chunked support does exist in the http package, but it doesn't work with
urllib.  Tracking in 4631.
