Location is less relevant, since it will show up as additions in the patch.

Put it wherever makes most sense in comparison to existing related
comments/README. I have no preference myself.

If its any consolation, I notice a common issue with patches is lack
of *explanatory* comments, as opposed to line by line comments. So
same review comment to 50-75% of patches I've reviewed recently, which
is also likely why.
