Remove code for old-style classes:
better_exchook2.py:238:62: E1101: Module 'types' has no 'InstanceType' member (no-member)
Command-line equivalent of 9a33c2a65 ("Make requesting login form password work on Python 3", 2020-04-14):
command/setup_config.py:167:36: E1101: Module 'linkcheck.director.console' has no 'encode' member (no-member)
Add missing argument:
plugins/parseword.py:141:31: E1120: No value for argument 'wrange' in function call (no-value-for-parameter)
Except for tests that include non-unicode characters:
tests/test_po.py
tests/test_strformat.py
tests/test_url.py
tests/checker/test_error.py
tests/checker/test_news.py
MS Word files are binary data, and get_temp_filename() will write them
to disk using open(..., 'wb'), so we want to pass bytes in there, not
Unicode.
See #323.
