[docs] [issue29133] Minor inaccuracy in shlex.shlex punctuation_chars example

[Berker Peksag]

Berker Peksag added the comment:

I'd probably write it without the for loop:

    text = "a && b; c && d || e; f >'abc'; (def \"ghi\")"

    result = shlex.shlex(text)
    print(f"Old behavior: {list(result)}")

    result = shlex.shlex(text, punctuation_chars=True)
    print(f"New behavior: {list(result)}")

Or just:

    >>> import shlex
    >>> text = "a && b; c && d || e; f >'abc'; (def \"ghi\")"
    >>> list(shlex.shlex(text))
    ['a', '&', '&', 'b', ';', 'c', '&', '&', 'd', '|', '|', 'e', ';', 'f', '>', "'abc'", ';', '(', 'def', '"ghi"', ')']
    >>> list(shlex.shlex(text, punctuation_chars=True))
    ['a', '&&', 'b', ';', 'c', '&&', 'd', '||', 'e', ';', 'f', '>', "'abc'", ';', '(', 'def', '"ghi"', ')']

(Adding Vinay to nosy list to get his feedback since he wrote the original example.)
