Re: [PATCH] git-gui: set GIT_DIR and GIT_WORK_TREE after setup

> Rather than juggling with the env var GIT_DIR around the invocation of
> gitk, set it and GIT_WORK_TREE after finishing setup, ensuring that any
> external tool works with the setup we're running with.
> 
> This also allows us to remove a couple of conditionals when running gitk
> or git gui in a submodule, as we know that the variables are present and
> have to be unset and reset before and after the invocation.
