From aeb090d5f7081a166357fa850950da89feb25e97 Mon Sep 17 00:00:00 2001
From: Alan McIntyre <alan.mcintyre@local>
Date: Thu, 5 Feb 2009 20:11:40 +0000
Subject: Issue #957: - Fix problems with test decorators when used on test
 generators. - The skip/fail arguments for skipif and knownfailureif can now
 be   either a bool or a callable that returns a bool. - Added tests for the
 test decorators.
