parse-options: refactor flags for usage_with_options_internal

When reading or editing calls to usage_with_options_internal, it is
difficult to tell what trailing "0, 0", "0, 1", "1, 0" arguments mean
(NB there is never a "1, 1" case).

Give the flags readable names to improve call-sites without changing any
behavior.
