Subject: Fixing an incorrect concatenate of CSS classes arrays
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=eeecf5a704bcd68bcb3add466f0e8c9af4f13fba;p=moodle.git

Fixing an incorrect concatenate of CSS classes arrays

array + array does not add new items if their numeric keys are the same. This
lead to the bug that add_classes() did not work correctly.
