Some clearing up.
The biggest change is to undo the chaining style of the `AWriter`
abstraction (a simplifer writer-like interface) and also used in settter for
`IndentedWriter`.
The chaining was to allow setters like `setLineNumbers` and output functions
`print` to chain:
```
AWriter out = IndentedWriter.stdout.clone().setLineNumbers(true);
out.println("foo").println("bar");
```
But this causes a lot of IDE warnings. The result of a chain-able method is
`this` but the IDE does not know that fact.
It looks to the IDE like a fresh AutoClosable resource and it suggests
try-with-resource. Only the outer resource needs that.
Fortunately, this is a primarily internal class, the chaining was added
recently at 5.0.0, and chaining has not been retro-applied much in the code
base.
