changegroup: inline prune() logic from narrow prune() needs to ellide manifests that aren't part of the narrow matcher. The code is violating storage abstractions, so a comment has been added. Keep in mind the impetus for moving this code to core is so changegroup code can be refactored to be storage agnostic. Differential Revision: https://phab.mercurial-scm.org/D4012
