I have installed some changes to fix this and other problems related
to line-move around such multi-line overlay strings.

The changes touches on some tricky low-level "move_it_..." functions
so I may have broken other things...

I also fixed problems with positioning the cursor on (first char of)
such multi-line strings.

Finally, I fixed problems related to vertical-motion not moving when
point is on an image.
