[issue18723] shorten function of textwrap module is susceptible to non-normalized whitespaces

[Vajrasky Kok]

Vajrasky Kok added the comment:

I missed this case:

>>> from textwrap import shorten
>>> shorten('hell', 4)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/sky/Code/python/programming_language/cpython/Lib/textwrap.py", line 386, in shorten
    return w.shorten(text, placeholder=placeholder)
  File "/home/sky/Code/python/programming_language/cpython/Lib/textwrap.py", line 322, in shorten
    raise ValueError("placeholder too large for max width")
ValueError: placeholder too large for max width

Also, in this patch, I removed the unnecessary stripping of the text part.
