Hi,
Thanks for your time & patience to review this PR.
We are researchers focusing on Rust unit tests. By examine the existing code, we found a unit test can be added to improve the repo's overall unit test coverage(this project is already been well tested).
We only manually changed our assert statements to make it consistent with existing unit tests and the newly covered code region is:
textwrap/src/refill.rs
Lines 77 to 80 in 872f221
Thanks again for reviewing.
