+/** I know what I am doing is wrong -- since I am about to look into
+ *  this bug, I add a test in pending/pos... however, I am afraid that
+ *  once this bug is fixed, this test case might go into test/pos
+ *  there it adds to the huge number of tiny little test cases.
+ *
+ * Ideally, an option in the bugtracking system would automatically
+ * handle "pos" bugs.
