[empathy: 2/4] Fix after review

[Dafydd Harries <daf src gnome org>]

commit d7cd12a662172eca0276c8bbe13fc1257e0d0609
Author: Gabriel Millaire <millaire gabriel gmail com>
Date:   Tue Sep 29 17:57:53 2009 -0400

    Fix after review
    - Early return if no selection
    - Now uses a for-loop with gtk_text_iter_equal
    - Renamed flag_return to ignore_newlines, same meaning
    - Improvement to string_append
