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?
|
|
|
|
The ability to define default values for method arguments can make a method easier to use. Default argument values allow callers to specify as many or as few arguments as they want while getting the same functionality and minimizing boilerplate, wrapper code.
|
|
|
|
|
|
But all method arguments with default values should be declared after the method arguments without default values. Otherwise, it makes it impossible for callers to take advantage of defaults; they must re-specify the defaulted values in order to "get to" the non-default arguments.
