[issue18585] Add a text truncation function

[Vajrasky Kok]

Vajrasky Kok added the comment:

Something is not right if we use more than one space.

>>> textwrap.summarize('hello      world!', width=12)
'hello world!'
>>> textwrap.summarize('hello      world!', width=11)
'hello (...)'
>>> textwrap.summarize('hello      world!', width=10)
'(...)'

I expect the last statement would give result: 'hello (...)' because 'hello' is just 5 characters, less than 10.
