Use new semantics of is_bare/inside_git_dir/inside_work_tree

Up to now to check for a working tree this was used:
	!is_bare && !inside_git_dir
(the check for bare is redundant because is_inside_git_dir
returned already 1 for bare repositories).
Now the check is:
	inside_work_tree && !inside_git_dir
