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"

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.
