Problem with --work-tree

Hi,

I've got the following problem. I've got a GIT repo at /home/nazgul/src/test-work-tree and I've got some changed files in this repo. I want to see this changes when a `git` runs outside this directory. I tried to run `git --git-dir=/home/nazgul/src/test-work-tree/.git --work-tree=/home/nazgul/src/test-work-tree diff-index --name-status HEAD` from my home directory. In such way diff-index tells me that all files from my repo has been deleted. I think it is because this command does not understand a --work-tree parameter. And I saw the same problem with a git diff command (something like that: git --git-dir=/home/nazgul/src/test-work-tree/.git --work-tree=/home/nazgul/src/test-work-tree diff).

I use git version debian.1.5.6.3.1

Is it my mistake or it is bugs in a GIT?
