Feature Request: Filter out original interface and fakes from "GoImplements"

[XenoPhex]

When I run "GoImplements" on an interface function, the first result is always the interface in question and then a list of fakes and implementers.

It would be nice if the fakes and the initial interface function were filtered out of this list.

This sounds like a feature request to https://github.com/fatih/vim-go rather than to this vimfiles repo. But I can think about it for a bit with you if you wish @XenoPhex
