[PATCH 01/13] apply: mark include/exclude options as NONEG

The options callback for "git apply --no-include" is not ready to handle the "unset" parameter, and as a result will segfault when it adds a NULL argument to the include list (likewise for "--no-exclude").

In theory this might be used to clear the list, but since both "--include" and "--exclude" add to the same list, it's not immediately obvious what the semantics should be. Let's punt on that for now and just disallow the broken options.
