Add Tests for Fixed Issues

This commit also changes the "fix" for text-only lines. We should be adjusting the text content as little as possible. In this case, we are still adding spaces (or tabs) after the last line break, but that is necessary to indent the closing element. I'll continue to adjust this as needed based on feedback and possibly add a setting to gate this behavior.
