[New-bugs-announce] [issue9553] test_argparse.py: 80 failures if COLUMNS env var set to a value other than 80

[Denver Coneybeare]

New submission from Denver Coneybeare <denver.coneybeare at gmail.com>:

If the COLUMNS environment variable is set to a value other than 80 then test_argparse.py yields 80 failures.  The value of the COLUMNS environment variable affects line wrapping of the help output and the test cases assume line wraps at 80 columns.  So setting COLUMNS=160, for example, then running the tests will reproduce the failures.  The fix is to invoke: os.environ["COLUMNS"] = "80".

A proposed patch for py3k/Lib/test/test_argparse.py is attached (test_argparse.py.COLUMNS.patch)
