[PATCH] emacs: make 'git-status' work with separate git dirs

From: Enrico Scholz <enrico.scholz@sigma-chemnitz.de>

Message-ID: <1353599934-23222-1-git-send-email-enrico.scholz@sigma-chemnitz.de>

when trying 'M-x git-status' in a submodule created with recent (1.7.5+) git, the command fails with

| ... is not a git working tree

This is caused by creating submodules with '--separate-git-dir' but still checking for a working tree by testing for a '.git' directory.

The patch fixes this by relaxing the existing detection a little bit.
