Anaphoric 'aand' macro added
Fix for moving to start or end of expressions

Specifically for implicit expressions

e.g.

(setf x 1
      y-!- 2  ; some comment
      )

Calling backward-up or backward-end will
move to the end of the comment. Now cursor
moves correctly to the end of the implicit
expression.
