Subject: Some small fixes to the category display:
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=f1c1b17ab5d9482e2565b48ff1184fc47c9eef85;p=moodle.git

Some small fixes to the category display:

  - small numbers of courses (less than 8) are displayed in full,
    unless the creator or admin is editing.

  - course counts are now accurate when all courses are removed from
    a category
