Probably want to move these helpers to a common spot, but I'm fine with that as
a followup later, maybe just add a TODO mentioning it.

[eakuefner, 2017/05/19 18:51:48]

Added TODO. It's true that moving these helpers to their own file will
eventually block deleting add_point_queue.

Maybe move this to _GetExtraArgs() or something to that effect?

Done and renamed to unit_args.
