Inline adoc when include has no additional value (#1940)
Inline adoc files when they are included exactly once.

Also fix language tags because this inlining gives us better information
on what language the code is written in.

== Why is this an issue?
When ``++sizeof++`` is used on a pointer, it returns the size of the pointer (4 or 8 bytes, depending on architecture and OS), not the size of the pointed-to memory area. Therefore, division of that value is not likely to yield what was intended.
=== Noncompliant code example
[source,cpp]
----
char* message = "hello world";
sizeof(message) / 4; // Noncompliant
