Subject: bug#6697: 24.0.50; Emacs doesn't show fringe marker at overlay-arrow-position

From: Tassilo Horn <[email-masked]>
Date: Wed, 21 Jul 2010 21:46:32 +0200

Start emacs 24 with emacs -Q, goto *scratch* and evaluate:

  (progn (setq overlay-arrow-position (make-marker))
         (set-marker overlay-arrow-position
                     (line-beginning-position)))

The expected result is the display of an arrow fringe marker at point's
line, or the display of an "=>" text marker (overlay-arrow-string) in
non-graphical frames.  But the current bzr trunk shows none of them.
