Bug #5902: Array#join with an unused, infected separator may or may not infect the result

=begin
It's infected if the separator is unused because there is only one element, but not if there are zero elements. Is this intended behavior?

  s = [].join(",".taint.untrust)
  s.tainted? #=> false
  s.untrusted? #=> false

  s = [1].join(",".taint.untrust)
  s.tainted? #=> true
  s.untrusted? #=> true
=end
