Jean-Marc Lasgouttes 34285cc683 Handle properly top/bottom of inset with mac-like cursor movement 
The correct behavior is to go to position 0 going up from first row,
and to end of row when going down on last row.

The targetx value of the cursor is not updated, which makes cursor
movement more natural.

Fixes bug #10701.
