GIT_DIR output from git worktree list

[Gabriel Nützi <gnuetzi@xxxxxxxxx>]

Hello,

When you do move the .git folder somewhere else:

git init Test && cd Test && mv .git .git-b

and then do

cd Test &&
git --git-dir=.git-b --work-tree . worktree list

the output is :
..../Test/.git-b  0000000 [master]

Why is the output a .git Dir and not a worktree. I expected `.../Test`.

Thanks for the help.
