Attaching updated patch based on Ezio and Antoine's comments.  Let me know if I'm not using the correct or preferred terminology around buffer objects and the buffer protocol.

It doesn't seem like the section on the buffer protocol actually says what objects implementing the buffer protocol should be called.  I gather indirectly from the docs that such objects are called "buffer objects" (as opposed to just "buffers"):
