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?
include::../description.adoc[]
=== Noncompliant code example
[source,kotlin]
----
when(param) { // missing else
1 -> doSomething()
2 -> doSomethingElse()
}
----
=== Compliant solution
[source,kotlin]
----
when(param) {
1 -> doSomething()
2 -> doSomethingElse()
else -> error("myMessage")
}
----
=== Exceptions
If the ``++when++`` clause is used as an expression, Kotlin compiler already enforces that all possible cases are covered with branch conditions. So no issue will be raised in this case.
Example:
[source,kotlin]
----
enum class Day {
SUNDAY, MONDAY
}
...
val myVal = when(day) {
MyEnum.SUNDAY -> 1
MyEnum.MONDAY -> 2
}
