+Subject: [PATCH] DNF 3: workaround a bug with config values that are lists
+
+There's a bug / overly-clever-design flaw in DNF 3 that prevents
+us appending to config values that appear to be lists, even
+though lists should be mutable objects and this *ought* to work
+(and did work in DNF 2):
+
+https://bugzilla.redhat.com/show_bug.cgi?id=1595917
+
+This works around it.
