I see you figured this out, but what I do is initial import:
import v1 to vendor/v1 copy vendor/v1 to vendor/trunk copy vendor/trunk to trunk nth import: import vN to vendor/vN merge --ignore-ancestry vendor/v(N-1) vendor/vN to vendor/trunk # note that now we have a vendor branch with stable ancestry merge vendor/trunk to trunk
