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 all the keys of a Map are values from the same enum, the ``++Map++`` can be replaced with an ``++EnumMap++``, which can be much more efficient than other sets because the underlying data structure is a simple array.
