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?
|

A ``++Do ... Loop++`` without a ``++While++`` or ``++Until++`` condition must be terminated by an unstructured ``++Exit Do++`` statement. It is safer and more readable to use structured loops instead.
