modinfo missing in get_my_courses

When you go to the My Moodle page, it shows a list of the courses you're in, but only the titles. If you have a high enough error_reporting level it will also show complains from the get_all_instances_in_courses function (in lib/datalib.php) about the 'modinfo' attribute missing from the course object. The reason for this is that the get_my_courses function (in lib/datalib.php also) doesn't get the modinfo attribute by default.

The fix is trivial, just add 'modinfo' somewhere in $d_fields in get_my_courses. In CVS right now, it's on line 689. I've included a patch to do it too.

Then other relevant data will show up on the My Moddle page to.
