bug fix: removed \r in textversion's content because of a comment position bug in pre_edit. Added a save function to TextVersionManager to do so. Also removed cleaning \r before computing diffs because it should not be necessary anymore.

from django.utils.translation.trans_real import translation

def translate_to(value, language_code):
    t = translation(language_code)    
    return getattr(t, 'gettext')(value)
