For usage in completion scripts. Unlike `__fish_is_first_token` (which is probably not correctly named), `__fish_is_first_arg` returns true regardless of whether existing tokens start with `-` or not, to be used when an arg cannot be used with any other argument. `__fish_prev_arg_in` is similar to `__fish_seen_...` but it explicitly tests the preceding token only, for arguments that take only a single parameter.
