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?
|
|
|
|
``++Symbol++`` is a primitive type introduced in ECMAScript2015. Its instances are mainly used as unique property keys.
|
|
|
|
An instance can only be created by using ``++Symbol++`` as a function. Using ``++Symbol++`` with the ``++new++`` operator will raise a ``++TypeError++``.
