At the moment, the get_string('fullname', 'moodle') is used for both course fullname (e.g. in course/edit_form.php) and for user fullname (e.g. admin/user/usert_bulk.php). This causes problems in languages where different words should be used for names of persons and for names of things.
There is a proposal to introduce new strings "coursefullname", "courseshortname" instead of current "fullname" and "shortname" and keep "fullname" (or even better new "userfullname") for user full name only.
