I don't think the land-commit-queue command makes sense. It's more robust to drive the commit-queue from another process. When we do that, we want to only commit patches that have the commit-queue+ flag, so we should make land-patches --commit-queue do the filtering.
This patch requires the infrastructure from Bug 27918.
