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?
It's slightly more efficient to append single characters to ``++StringBuffer++`` and ``++StringBuilder++`` instances as ``++char++``s, than as ``++String++``s. That is, it's more efficient to put a single ``++char++`` in single quotes, rather than double quotes.
=== Noncompliant code example
[source,java]
----
StringBuilder sb = new StringBuilder();
sb.append("a"); // Noncompliant
----
=== Compliant solution
[source,java]
----
StringBuilder sb = new StringBuilder();
sb.append('a'); // Noncompliant

I really doubt this one should be activated by default. This is really something that you should activate either, to be anal on your style or because you have a perf critical application that actually cares about this, so any way I would not include it in default profile.
