Function difft::lines::split_on_newlines

pub(crate) fn split_on_newlines(s: &str) -> impl Iterator<Item = &str>

Split s on \n or \r\n. Always returns a non-empty vec. Each line in the vec does not include the trailing newline.

This differs from str::lines, which considers "" to be zero lines and "foo\n" to be one line.
