…ually exclusive group are suppressed (pythonGH-96311) Reproducer depends on terminal size - the traceback occurs when there's an option long enough so the usage line doesn't fit the terminal width. Option order is also important for reproducibility. Excluding empty groups (with all options suppressed) from inserts fixes the problem.
