How is it possible?

in a git repository

    $ GIT_WORK_TREE=../other-dir git rev-parse --is-inside-work-tree
    false

Work tree root should be a parent of cwd, otherwise `rev-parse
--is-inside-work-tree` returns false -> git repository not detected.
And there is only one path from cwd to the root -> all parents of cwd
are parents or subdirs to each other.
