Trailing blank rows in dependencies block are not removed

tidy-m-p staged v1.0.0
Maven 3.3.3 on Oracle JDK 1.7.0_79 on Windows 7.

For this snippet:

```
<dependencies>
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>


</dependencies>
```

I'd like the trailing blank rows to be removed (before the close dependencies tag), which they aren't.
