From: Johannes Schindelin <johannes.schindelin@xxxxxx> When Git wants to spawn a child Git process inside a worktree's subdirectory while `GIT_DIR` is set, we need to take care of specifying the work tree's top-level directory explicitly because it cannot be discovered: the current directory is _not_ the top-level directory of the work tree, and neither is it inside the parent directory of `GIT_DIR`. This fixes the problem where `git stash apply` would report pretty much everything deleted or untracked when run inside a worktree's subdirectory. To make sure that we do not introduce the "reverse problem", i.e. when `GIT_WORK_TREE` is defined but `GIT_DIR` is not, we simply make sure that both are set.
