Make sure that includes are always surrounded by empty lines (#2270)
When an include is not surrounded by empty lines, its content is inlined
on the same line as the adjacent content. That can lead to broken tags
and other display issues.
This PR fixes all such includes and introduces a validation step that
forbids introducing the same problem again.

== Why is this an issue?
There's no valid reason to test ``++this++`` with ``++instanceof++``. The only plausible explanation for such a test is that you're executing code in a parent class conditionally based on the kind of child class ``++this++`` is. But code that's specific to a child class should be _in_ that child class, not in the parent.
=== Noncompliant code example
[source,java]
----
public class JunkFood{
public void doSomething() {
if (this instanceof Pizza) { // Noncompliant
// ...
} else if (...
}
