Nothing special is done for buffer reading.  It is the same functionality
that allows isearch to search the minibuffer history: C-r starts searching
the history list backwards, and C-s starts searching the "future" history.

This already works in all minibuffers, and this patch just puts the buffer
list to the "future" history of C-x b.
