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.

== Sensitive Code Example
Any users can use the key:
[source,kotlin]
----
val keyGenerator: KeyGenerator = KeyGenerator.getInstance(KeyProperties.KEY_ALGORITHM_AES, "AndroidKeyStore")
var builder: KeyGenParameterSpec = KeyGenParameterSpec.Builder("test_secret_key", KeyProperties.PURPOSE_ENCRYPT or KeyProperties.PURPOSE_DECRYPT) // Noncompliant
.setBlockModes(KeyProperties.BLOCK_MODE_GCM)
.setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_NONE)
.build()
keyGenerator.init(builder)
----
== Compliant Solution
The use of the key is limited to authenticated users (for a duration of time defined to 60 seconds):
