Reviewing this I see that the case "unit only without int" is not 
documented now. This has been changed already in 50e5d024.
Probably no problem because it's only --help and not info page. Just 
want to note that.

Saying "and/or" instead of "and" could make it narrowly but still not 
100% exactly and more confusing again.
