* Add trailing newline on non-empty list in unlines There are several reasons to do that: * a line in a text file is something which ends with newline, and the last line is not special * `unlines []` should be different from `unlines [""]` * `unlines (a ++ b) = unlines a ++ unlines b` * Haskell does it * Change lines function behaviour
