Close #1210
The proposed implementation of
rewrite_string
relies less on manual handling of ranges within the string, which I find (subjectively!) easier to reason about. If you prefer the previous logic, I will modify this PR accordingly.In addition, this rewrite keeps the
max_width
argument although it is unused ATM, for reasons described in a comment of the issue. I will change this PR as per the comment's response.
