These changes are related to my fix for the ignored unit test. If I apply
my fix but keep the master version of this file, 24 unit tests fail. If I apply
my fix along with this file diff then all tests pass, including the test that
is currently ignored.
I'm not sure I can develop a unit test for this current commit that should
pass but will fail without this file's changes. I haven't spent any time
thinking about it, and I really need to work on other things right now.
If you want I will back out this change. However, I will re-incorporate it
in a follow-on PR.
Thanks.
