stats don't show day names in course or user language

In testing another bug, I went to the Italian Moodle course. I was looking at my profile as it is displayed in that course, and in particular, my statistics. I noticed that the abbreviations for the day names on the page:

http://moodle.org/course/user.php?id=38&user=13946&mode=alllogs

were English, not Italian. So I decided to switch my site language to Italian, but still the day name abbreviations are in English. It seems to me these should be translated like everything else is. It seems to me this should be possible since the word "Accessi" is written up the side, not the English equivalent, so if it can be done for that word it can be done for the day names as well.
