The RFC is bit hard to understand on this point, but the examples
clearly show that parameter values that are encoded according
to its charset/language rules don't have surrounding quotes, and
the ABNF does not allow for quotes.  So when we produce such
encoded values, we no longer add quotes.

New output looks like this:

Traceback (most recent call last):
  File "test.py", line 5, in test_ce
    self.assertCountEqual('abracadabra xx', 'simsalabim xx')
AssertionError: Element counts were not equal:

Addition OKed by GB on IRC (R. David Murray). No backport.

part of the iterator had been consumed.   Also, fix argument names which
did not match the docs and were a bit misleading.

Original patch by Thomas Herve.

self.handlers is still used in one urllib2 test, but not by the code iteslf.

for identifiers.  Fixed the documentation to agree.

Previously passing a string in as the password would fail either with
an assertion error or a TypeError with a confusing error message.
Note that a string can't be accepted since zipfile has no way to
guess what encoding should be used to turn it into bytes.
