tweaks: elide two parameters and thus a pair of wrapper functions 

When just scrolling and the cursor does not need to change position
(that is: it is not on the first or last row of the edit window),
then edit_scroll() has handled everything and there is no need to
additionally redraw anything or update 'placewewant'.
