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.

Arfrever Taifersar Arahesis reported that test_compileall failed during Gentoo
install because it was tyring to write .pyc files to a read-only system
directory during test_no_args_compiles_path.  Having the tests call python
with -S should eliminate the system directories from the path.

Surprisingly, it turns out there was no test that exercised this code path.
