ranslators could test if the translated string doesn't breaks the interface.

i am not sure if i really have to patch get_string or can do this in a more "kindly" way.
first i've considered a filter, but it applies only to user content, not moodle strings.

By modifiyng get_string i mean first check if there is any staged translation for the requested string and return it (maybe surroundd by a span to be treated by the theme) instead of search in $strings array
