Hi,

I found an issue where evaluating this line or not causes Emacs behaviour
change:

(format "%s" marked-point)


"marked-point" is a marker.  The bug was found on NTEmacs 23.2.1, reproed on
CVS NTEmacs 20110111, and Stephen Berman confirmed it on GNU Emacs 24.0.50.1
(i686-pc-linux-gnu, GTK+ Version 2.20.1) of 2011-01-13 on escher

"rebox2_bug.el" is attached to this message.

Repro-steps:

   1. emacs -Q rebox2_bug.el
   2. M-x eval-current-buffer
   3. C-x b<enter> ;; switch to "*scratch*"
   4. M-x rebox-mode
   5. M-<
   6. SPC,SPC ;; space twice
   7. C-aC-aC-aC-a ;; notice that the point is stuck at 6
   8. C-xb<enter> ;; switch to "rebox2_bug.el
   9. M-g g 1714
   10. C-d ;; uncomment the hack workaround the bug
   11. C-M-x ;; reevaluated the function
   12. C-x b<enter> ;; switch to "*scratch*"
   13. C-aC-aC-aC-a ;; notice that the cursor switches between 1 and 6
