Entering a submodule clears GIT_DIR and GIT_WORK_TREE, as it must: they say where the superproject is. But the stack we push the superproject onto so that escape brings us back only held its path, and for a repo opened with --git-dir/--work-tree the path leads nowhere — git can't find a repo there. Escaping out of a submodule of a dotfile repo failed with "not a git repository", or, if some unrelated repo happened to lie above the work tree, quietly switched to that one instead. Push the environment onto the stack along with the path, taken from the repo paths rather than from the process env, so that it also covers a repo we worked the location out for ourselves.
