TODO: <a href="https://golang.org/cl/345569">https://golang.org/cl/345569</a>: add Writer.AvailableBuffer
The new <a href="/pkg/bufio#AvailableBuffer"><code>Writer.AvailableBuffer</code></a>
method returns an empty buffer with a possibly non-empty capacity for use
with append-like APIs. After appending, the buffer can be provided to a
succeeding <code>Write</code> call and possibly avoid any copying.

TODO: <a href="https://golang.org/cl/345570">https://golang.org/cl/345570</a>: make Reader.Reset and Writer.Reset work on the zero value
The methods <a href="/pkg/bufio#Reader.Reset"><code>Reader.Reset</code></a> and
<a href="/pkg/bufio#Writer.Reset"><code>Writer.Reset</code></a>
now use the default buffer size when called on objects with a
<code>nil</code> buffer.
