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?
|
|
|
|
Comparing dissimilar types using the strict equality operators ``++===++`` and ``++!==++`` will always return the same value, respectively ``++false++`` and ``++true++``, because no type conversion is done before the comparison. Thus, such comparisons can only be bugs.

Remove this ["==="|"!=="] check; it will always be [false|true]. Did you mean to use ["=="|"!="]?
