Then it wouldn't match those:

./builder/dockerfile/copy_windows.go:   cmd := reexec.Command("windows-fix-permissions", source, destination, identity.SID)
./daemon/graphdriver/overlay2/mount.go: cmd := reexec.Command("docker-mountfrom", dir)
./daemon/graphdriver/windows/windows.go:                cmd := reexec.Command(append([]string{"docker-windows-write-layer", d.info.HomeDir, id}, parentLayerPaths...)...)
./pkg/chrootarchive/archive_unix.go:    cmd := reexec.Command("docker-untar", dest)
./pkg/chrootarchive/diff_unix.go:       cmd := reexec.Command("docker-applyLayer", dest)

Why did you change it?
