Re: [PATCH 09/14] tree-diff: inline path_appendnew()

> Our path_appendnew() has been simplified to the point that it is mostly
> just implementing combine_diff_path_new(), plus setting the "next"
> pointer. Since there's only one caller, let's replace it completely with
> a call to that helper function.
