Strange behavior of mv(1)

Hi,

It seems that mv(1) behaves differently when handling with respect to
different filesystems.

Test1: Moving within one filesystem:

mkdir -p t/a/b
mkdir -p b/c/d
cd t/
mv ../b a

Resulting tree:
	t/
		a/
			b/
				c/
					d/

However, with different filesystems:

mkdir -p t/a/b
mkdir -p /tmp/b/c/d
cd t
mv /tmp/b a

We get:

	t/
		a/
			b/
				b/
					c/
						d/

I think the second behavior is not correct?

Cheers,
