Interestingly, the first time you do this, there's no adjustment from
14 to 15. Sounds like some snafu with the last point position?
I can confirm that this happens because point adjustment: setting
global-disable-point-adjustment to non-nil eliminates the problem:
point stays at position 14.
Also, C-e behaves correctly no matter what. So it's something
specific to end-of-visual-line or vertical-motion.
Perhaps stepping through adjust_point_for_property with a debugger
will show what's wrong.
