### Width/Padding calculation example

This is just a little bit of Rust to ensure we're roundtripping code blocks
correctly:

```
if width < 60 {
    wrap_width = width - 1; // leave space for cursor at the end of the line
    left_padding = 0;
} else if width < 100 {
    wrap_width = width.saturating_sub(2);
    left_padding = 2;
} else {
    left_padding = (width.saturating_sub(100)) / 2 + 4;
    wrap_width = width.saturating_sub(left_padding);
}
```


The end.
