Introduction of upstream_arg in this step looked a bit
surprising, but the hook invocation is the only thing that uses it,
so it is understandable.
"rebase: handle the re-rebase hook and --no-verify" would have been
sufficient, without "add" or parentheses.

Do we need to catch "--no-no-verify" ourselves with NONEG bit, or is
this sufficient to tell parse_options() machinery to take care of
it?
