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?
|
|
|
|
Operators https://docs.python.org/3/reference/expressions.html#is-not[``++is++``] and https://docs.python.org/3/reference/expressions.html#is-not[``++is not++``] check if their operands point to the same instance, thus they will always return respectively True and False when they are used to compare objects of different type. Such comparisons can only be bugs.
