I agree -- it makes intuitive sense for it to work that way, and I
firmly believe that people *do* use it that way already (as per the
example given), as the documentation always presented examples with
the nil case first, and therefore following its example would result
in that intuitive functionality (except in 26.1).

I'd like to see this fixed in 26.2, as I feel it's a very unexpected
change which can break things for users in confusing ways.
