Review Comment:
I think we could do this with source.chars() and get almost the same
results, except for very rare cases where multiply unicode characters make up a
single graphical grapheme

Review Comment:
Can you also add a test for
1. an even longer expression? One that would take 100 lines or something? I
think there should also be a maximum length limit
2. a predicate with exactly the render width
3. A predicate with the render width + 1
