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 ???
