Inject width via pylib to argparse formatter `argparse.HelpFormatter` looks at `$COLUMNS` only, falling back to a default of 80. `py.io.get_terminal_width()` is smarter there, and could even work better with https://github.com/pytest-dev/py/pull/219. This ensures to use a consistent value for formatting the ini values etc.

The HelpFormatter uses ``py.io.get_terminal_width`` for better width detection.
