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?
|
|
|
|
Calling the ``+``, ``++-++`` or ``++NOT++`` prefix operator twice does nothing: the second invocation undoes the first. Such mistakes are typically caused by accidentally double-tapping the key in question without noticing.
|
|
|
|
|
|
Either this is a bug, if the operator was actually meant to be called once, or misleading if done on purpose.

=== Noncompliant code example

|
|
|
[source,sql]
|
|
----
|
|
IF NOT ( NOT foo = 5 ) THEN -- Noncompliant
|
|
value := ++1; -- Noncompliant
|
|
END IF;

=== Compliant solution
|
|
|
|
[source,sql]
|
|
----
|
|
IF foo = 5 THEN -- Compliant
|
|
value := +1; -- Compliant
|
|
END IF;
