In principle, there would be "a true" solution,
but as you see, it's not quite possibly (by that means):

> op <- options(width=7)
Error in options(width = 7) : 
  invalid 'width' parameter, allowed 10...10000
> op <- options(width=10)
> 1:10
 [1]  1  2
 [3]  3  4
 [5]  5  6
 [7]  7  8
 [9]  9 10
> 1000+ 0:9 ## works for these
 [1] 1000
 [2] 1001
 [3] 1002
 [4] 1003
 [5] 1004
 [6] 1005
 [7] 1006
 [8] 1007
 [9] 1008
[10] 1009

In principle, the lower bound (10) for the width option could be
lowered a bit more, as I think 10 had been a somewhat arbitrary
choice protecting useRs from hanging themselves..
