Assuming people don't end with "\n", that will have the same effect as
doing it without the join:

irb(main):007:0> people = %w{ me you him her them }
=> ["me", "you", "him", "her", "them"]
irb(main):008:0> puts people[0..4].join("\n")
me
you
him
her
them
=> nil
irb(main):009:0> puts people[0..4]
me
you
him
her
them
=> nil

If they do end with "\n", then they'll be separated by blank lines if
you do the join.
