I think the parent poster meant that two newlines in file are displayed as an empty line. That's ok. What's odd is that the cursor is allowed to stay in the empty line, as if it was on a virtual character at the end of the line. However, if the line is not empty, the cursor is not allowed to go one character right of the last one.
