New submission from Adam Byrtek <[email protected]>:
Code snippet from optparse.py:
344 self.help_position = min(max_len + 2, self.max_help_position)
345 self.help_width = self.width - self.help_position
Where self.width is initialized with the COLUMNS environment variable. On
narrow terminals it can happen that self.help_position < self.width, leading to
an exception in textwrap.py:
raise ValueError("invalid width %r (must be > 0)" % self.width)
ValueError: invalid width -15 (must be > 0)
A reasonable workaround would be to trim part of the help text instead of
causing an exception.
