The '--git-dir' command-line option also sets this value.
'GIT_WORK_TREE'::
- Set the path to the working tree. The value will not be
- used in combination with repositories found automatically in
- a .git directory (i.e. $GIT_DIR is not set).
+ Set the path to the root of the working tree.

option and the core.worktree configuration variable.
