OK.

According to the documentation on overlay-arrow-string:

    String to display as an arrow.  See also `overlay-arrow-position'.

Whatever I set overlay-arrow-string to I get a little bitmap arrow ">".

AKA the following source code displays an arrow:

- ------------

(make-local-variable 'overlay-arrow-string)

(setq overlay-arrow-string "asdf")

(let(m)

  (setq m (make-marker))

  (set-marker m 1)
        
  (setq overlay-arrow-position m))


- -----------

All of the source in Emacs sets this to "=>".  What is the difference?  Can one
display anything other than an arrow?

Also, shouldn't this variable be make-variable-buffer-local'd ???
