+
+    Add __bool__() / __nonzero__() method to python rpmmi objects (ticket #153)
+    - Objects supporting __len__() use (len > 0) for boolean representation,
+      which normally makes sense but as the match iterator count is often
+      zero despite the iterator actually existing and returning something,
+      and breaks existing code (rpmlint at least)
+    - Adding a __bool__() (known as __nonzero__() in Python < 3) method
+      returning true for non-NULL iterator fixes this and gives more
+      meaningful answers than pre 4.8.0 which simply always returned True
