[issue43518] textwrap.shorten does not always respect word boundaries

[annesylvie]

New submission from annesylvie <annesylviedeutsch at gmail.com>:

The `shorten` function from the `textwrap` module does not always break strings at the correct location.

`shorten("hello world!", width=7, placeholder="")`
 returns
`'hello'`
as expected, but
`shorten("hello world!!!!!!", width=7, placeholder="")`
returns
`'hello w'`
which is incorrect. The error seems to appear when two or more exclamation marks (in this specific example) are added.
