Is there a specific example, that is formatted wrongly because of it?

[yuyi98]

			ast.Block {
				if node is ast.Block && !node.is_unsafe && node.pos.line_nr - prev_line_nr > 1 {
					return true
				} else {
					return false
				}
			}

node.pos.line_nr - prev_line_nr > 1 Indicate blank line, originally it was node.pos.line_nr - prev_line_nr > 0.

[spytheman]

Yes, I can read the diff, and I did so.

My question is about an example of code, that would have been formatted differently before, but is now correct on this PR.

[yuyi98]

I see, I'll add one.

[yuyi98]

fn main() {
	{
		println('(1/3) My first small scope')
		//
	}

	println('hello')
}

Thank you.
