Thanks. GitHub is showing some weird diffs. I suspect it is due to whitespace. Can you make sure this is using soft tabs (4 spaces) instead of hard tabs?

I saw that as well. I did use soft tabs and for some reason its still
showing the weird diffs.

Might be because I used the new Github for Windows client. Should I try
doing a new commit or is there an easier way to fix the whitespace diff
issues?

In the client window it shows the diffs correctly: http://i.minus.com/iwzeIYs9E5zXY.png

It was the ^M at the end of the lines. dos2unix.exe fixed it. Will recommit fixed version

Great. That was going to be my next question but looks like you found it already. I'll review, merge, and tag it this evening.

Please add some unit tests for this handler (e.g. see the testJsonResponseParse test in HttpfulTest.php). There is decent test coverage and I'd like to keep that up. Thanks!
