String#lines is essentially the same as String#each, which is gone in
1.9. You get, instead of #each and friends (Enumerable), a whole
toolkit of ways to enumerate through strings:

   * lines
   * bytes
   * chars
   * codepoints

There's no auto-chomping, but there never has been in any string
operation I can think of.
