Hmm, I couldn't test on Windows, and my previous patch worked on Mac
OS X (both X11 and Carbon) and Solaris for the original problem.

Maybe you can find such traces by setting a breakpoint to
current_column with the condition `Vinhibit_point_motion_hooks ==
Qnil'.  I found the following cases:

  pos_visible_p -> display_mode_line
  echo_area_display -> redisplay_mode_lines -> display_mode_lines -> 
display_mode_line
