Here cwd is /tmp/.elisp/flx but "setup: cwd: " returns /tmp/clayoven/.elisp/flx. The COMMIT_EDITMSG path is ../../.git/modules/.elisp/flx/COMMIT_EDITMSG. If you follow the former cwd (without symlink resolution), you end up at /tmp/.git/modules. If you follow the latter cwd, you end up at /tmp/clayoven/.git/modules... I think instead of letting the kernel walk the path, emacs does it by itself. Still looking for documents about this behavior..
