git-gui currently uses its own logic to determine the work-tree setting but 'git rev-parse --toplevel' directly returns git's work-tree value by calling get_git_work_tree() and is therefore always correct. This fixes an inability to handle some repository configurations. In particular where .git is a file containing a path to the real directory (a cross-platform symbolic link). To continue to support older versions than 1.7.0, setting the work-tree by normalizing the --show-cdup value is more reliable as git-dir might be outside the work-tree entirely.
