[slime-devel] Inserting images into the REPL

What follows is a patch to SLIME-REPL-EMIT which allows a cool hack:
inserting images into the REPL.  I find it useful when experimenting
with graphics-related code.  CL code:

(defun insert-image-into-repl (filename)
       (lambda ()
         (insert-image (create-image ,filename))
         (insert #\Newline)))

(SLIME-ENABLE-EVALUATE-IN-EMACS needs to be true to make this work.)
