Note that that the merge will fail with "...which is not *yet* supported" (emphasis added). It's probably going to be a long time before we support that case, because it will probably involve indicating the in the mergestate which side of the merge to indicate which side of the merge to choose for these files outside the narrowspec. But that's far enough away that it shouldn't block this patch. I'm mentioning it here just so others know what my plans for that were.
