[climacs-devel] adding forward- and backward object to the buffer protocol

[Robert Strandh]

Hello,

I am thinking of adding forward-object and backward-object to the
buffer protocol.  There are two reasons for this:

  * They are used much more often by client code than I hade initially
    imagined. 

  * In a line-oriented buffer implementation, they can be implemented
    MUCH more efficiently that with the current method of using
    (incf (offset mark)).  In fact the current method may be quite
    slow in such a buffer implementation. 

Any objections?
