diff options: Introduce --ignore-submodules
The new option --ignore-submodules can now be used to ignore changes in
submodules.
Why? Sometimes it is not interesting when a submodule changed.
For example, when reordering some commits in the superproject, a dirty
submodule is usually totally uninteresting. So we will use this option
in git-rebase to test for a dirty working tree.
