remove ambiguity between paths and treeishs

When calling commands that accept treeish and path arguments and there is a path with the same name as a treeish git cowardly refuses to pick one and asks for the command to use the unambiguous syntax where '--' seperates the treeish from the paths.  Add '--' to the git commands to indicate that the argument is a treeish and not a path.
