If you source the following script:
-------------------------------------------------------------------------------------
10new
20vnew
call setline(1, repeat('aa ', 200))
setlocal breakindent breakindentopt=shift:4 linebreak showbreak=>>
setlocal number
set cpo+=n
normal 12gj
redraw!
normal $
redraw!
-------------------------------------------------------------------------------------
You will see that the cursor is positioned a few characters before the end
of the line and it cannot be moved to the end of the line. Also, if you move
the cursor to the left by pressing "h" quite a few times (to cause the
screen
to scroll down), you will see the cursor can be positioned on the
'showbreak' characters.
