Display problem when there are no fringes present

[Nick Roberts]

Symptoms:



Set fringes to none                     M-x fringe-mode <RET> none <RET>
Instrument next-line for Edebug         C-u ESC C-x
Move the cursor down a line             <down>
Step through next-line                  <SPC>...

while stepping through the lines:

        (condition-case nil
            (line-move arg)
          ((beginning-of-buffer end-of-buffer) (ding)))

the text shifts left towards the overlay arrow.
