forget: support forgetting explicit paths in subrepos Change the behavior of the forget command such that explicit paths in subrepos are handled by forgetting the file in the subrepo. This eliminates the previous behavior where if you called "hg forget" for an explicit path in a subrepo, it would state that the file is already untracked.
