The JSON link at the bottom of  https://android.googlesource.com/ is not valid JSON

https://android.googlesource.com/?format=JSON

It starts with ")]}'" at the front of the file?  Maybe this is an attempt at JSONP
gone wrong?

I should note that this is not particularly important to me.  (I'm not trying to use
this part of the JSON api, just noting the error.)

This is an intentional feature to prevent cross-site scripting from reading the content
of the JSON response by way of a <script>var data = </script><script src="https://android.googlesource.com/?format=JSON">
tag.
