Fix for dot bug. See #22

[RobertStewart]

This pull request has more changes in it then just handling keys that improperly contain dots. Can you please remove the second commit from the pull request so I can merge just the first change?

I'd also like to have a unit test to prove the change works as described. I can always add one after I merge the pull request, or you could add one. Either way works for me.

One thing that surprised me about GitHub is that if you make additional commits on a branch, they automatically get added to any open pull request on that branch. So, I now create feature branches for every change that I plan to submit as a pull request. Then, I can much more easily control which commits end up in a pull request.

Yes that is exactly my problem now. The 2nd commit was not for this issue. :-( I'll try to remove it from the request.

OK, I revert the commit so the pull is now possible. It would be great if you can add a unit test.
