Change Unicode output handling in CLI*

This revisits the `hack' that I implemented in bc9b52419ea because I
noticed today (after integrating [1]) that the wrapping of sys.stdout
disables libreadline support in interactive prompts [2] which means
readline hints are printed to stdout instead of being interpreted by
libreadline, making interactive prompts rather hard to read :-s.

[1] humanfriendly.prompts.prompt_for_confirmation()
[2] input() and raw_input()
