Subject: [PATCH] MDL-13379 mnet: course overview at my home page displays
 remote courses, too

The patch submitted by Hubert Chathi. I just changed it a bit to use
moodle_url instead of string URLs and to use s() instead of format_string()
when putting the course fullname into title="" attribute value.
