Ah ok, I've misunderstood this feature probably perhaps
because, at first sight, I found the display looks "strange"
when some of the numbers have large imaginary parts as it
tends to make the delimitation between columns of numbers
less visible. E.g.,

> options(width=80)
> print(rep(c(1+1i, 1-1i, 1+1000i), 8))

And if there's less than a line of numbers I find it's
more natural to write :

>  print(c(1+1i, 1-1i, 1+1000i))
[1] 1+1i 1-1i 1+1000i

instead of what is actually printed :
[1] 1+   1i 1-   1i 1+1000i


Anyway, sorry this "bug" report.
