Is the diff suppose to be here? The function was defined in header file but not
implemented before your patch?

[cjgrant, 2016/10/28 14:16:58]

This was intentional.  I'm just moving the function to match the (better) order
in the header file.

[bshe, 2016/10/28 14:33:14]

hah. I missed the deleted function..
