re-word description of arg0namespace

It's unclear at first reading whether "may contain only one element"
means "elements >= 1, as an exception to the usual rule that
elements >= 2" (which is what was intended), or "elements == 1".

"Like a bus name or interface name" is a little ambiguous because they
have different syntactic restrictions: specifically allow any valid bus
name, which also allows all interface names.
