Fix console clear screen in case of partial scrolling
Commit d7586cb incorrectly checked only for the new cursor position
beyond the old cursor position to decide if we have to correct for user
scrolling. Since this situation is handled just fine if the cursor is
still visible, only perform the subsequent correction if the cursor is
not in the visible console window.
