Here's your reduced testcase. Just point mygit to a HEAD build.

  #!/bin/sh

  mygit=~/src/git/git
  cd /tmp
  $mygit clone https://github.com/artagnon/clayoven
  cd clayoven
  $mygit submodule add https://github.com/lewang/flx .elisp/flx
  $mygit commit -a -m "Added submodule"
  cd /tmp
  ln -s clayoven/.elisp
  cd .elisp/flx
  EDITOR="emacs -Q" git commit --amend
  # buffer-file-name = "/tmp/.git/modules/.elisp/flx/COMMIT_EDITMSG"

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..

Note that this is emacs 24.3. I used -Q to make sure that none of my
init magic (magit etc.) was responsible for changing directories or
doing something equally stupid. However, considering that it's
impossible to reproduce the problem with either cat or vim as the
EDITOR, you might be inclined to classify this as an Emacs bug. In
that case, why can't I reproduce it without submodules?

I'm going off to eat cake before I tear my hair out in frustration.
