X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=9a41d8a1f1e1c265f43d9e7f3d23f11f429a43a6;p=moodle.git

MDL-11784 - On the role assign page, list who is assigned the role for roles with only a few assignments. Improved version. Now, it only shows the extra column if some roles have between 1 and 10 assignees, as per Martin D's request. Merged from MOODLE_19_STABLE.
