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.

;;; Commentary:
 | 
						|
 | 
						|
;; This file contains an interface for the git version control
 | 
						|
;; system. It provides easy access to the most frequently used git
 | 
						|
;; commands. The user interface is as far as possible identical to
 | 
						|
;; that of the PCL-CVS mode.
 | 
						|
;;
 | 
						|
;; To install: put this file on the load-path and place the following
 | 
						|
;; in your .emacs file:
 | 
						|
;;
 | 
						|
;;    (require 'git)
 | 
						|
;;
 | 
						|
;; To start: `M-x git-status'
 | 
						|
;;
 | 
						|
;; TODO
 | 
						|
;;  - diff against other branch
 | 
						|
;;  - renaming files from the status buffer
 | 
						|
;;  - creating tags
 | 
						|
;;  - fetch/pull
 | 
						|
;;  - revlist browser
 | 
						|
;;  - git-show-branch browser
 | 
						|
;;
 | 
						|
 | 
						|
;;; Compatibility:
 | 
						|
;;
 | 
						|
;; This file works on GNU Emacs 21 or later. It may work on older
 | 
						|
;; versions but this is not guaranteed.
 | 
						|
;;
 | 
						|
;; It may work on XEmacs 21, provided that you first install the ewoc
 | 
						|
;; and log-edit packages.
