But do you think if it works with merge (ie. a partial merge)?

There's probably no interest in partial merge now, but if narrow clone
comes, index will be also narrowed and at least fast-forward merge
should work. I think it may work, but I'm not sure. unpack_callback()
and traverse_trees() look like magic to me. There may be some
interactions between index and unpacked trees that make partial merge
fail in a subtle way.
