CharBuffer may need special attention. It implements both Readable and 
Appendable and additional creates the potential for 
BufferOverflowException or ReadOnlyBufferException when the target is a 
CharBuffer. This is only so much that the javadoc in Readable can 
specify of course.

One possibly is to override the method in CharBuffer so that you can 
clarify some of this behavior. This would allow you to specify that it 
works like target.put(src) when both are char buffers for example - that 
probably is a nice property to specify anyway.

Are you planning to add an @implSpec to specify the default implementation?
