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?
Developers may define a list named ``++__all__++`` in a module to limit the names imported from it by wildcard imports (``++from mymodule import *++``). This list can only reference defined names, otherwise an ``++AttributeError++`` will be raised when the module is imported.
=== Noncompliant code example
[source,python]
----
from mymodule import my_func
__all__ = ["unknown_func"] # Noncompliant. "unknown_func" is undefined
----
=== Compliant solution
[source,python]
----
from mymodule import my_func
__all__ = ["my_func"]
