When I run z, I see paths with embedded ../ instead of the resulting cwd after changing directory. The path I expect to see is much lower.

$ z
0.000	/home/sam/go/src/foo/bar/../../baz/baz/
...
64.50	/home/sam/go/src/baz/baz/

Not sure if this is a bug, but I'm filing this based on our IRC conversation.
