This assertion fails due to str::lines() in Rust ignores final empty line, and thus the assertion would fail: https://doc.rust-lang.org/std/primitive.str.html#method.lines

Reading the source code shows that str::lines() uses .split_terminator('\n'). Instead we should just split ourselves with .split('\n'). This is a quick fix I'll do right away
