String#lines wasn't defined in 1.8.6 so I did not think there was any
precedence for it. My use case has always been (as Radoslaw said):

  "first line\nsecond line\nthird line".split("\n")

Wanting my program to read better, I have often defined #lines to do
just that. In my experience that's the frequent case. Wanting to keep
the separator I think is the lesser need --for which I would be
happier with a less concise method name. As it stands #lines does me
no good now.

  "first line\nsecond line\nthird line".lines.map{ |s| s.chomp("\n") }

Is even worse than before! ;)
