Precisely David. No implementations that I can test with produce a 
scrollbar. If you can narrow the viewport to allow the text to wrap, the 
second line overflows towards the left but is partially hidden by the 
width of the negative margin. If the test did once produce a scrollbar 
in any implementations (guessing Gecko 1.7 or Opera 7 or other UA) then 
such implementations allowed (or allows) visible horizontal overflow in 
both directions.
