Message 124343 - Python tracker

Also, I am not familiar with the backward-comparability requirements of py3k, but orsenthil's patch will break py3k code that relies on data being a string, shouldn't this be mentioned somewhere?

Finally, I do not understand why my proposed change, which is to add

+    if not data:
+        request.add_unredirected_header('Content-length', '0')


so that code that relies on being able to pass a blank string as data (for instance, the code in test_urllib2.py) is still able to do so.
