Subject: [Rd] intersect() change of behavior in 4.2
Message-ID: <CABtg=K=tRMdLJ7p2JHdFyOYVyjmLNszQguKn569gx+FswChtyw@mail.gmail.com>

I wonder if this change is intentional, and if it is, whether it is
worth mentioning in the NEWS.

? R-4.1 -q -e 'intersect(list(), "foo")'
> intersect(list(), "foo")
character(0)

? R-4.2 -q -e 'intersect(list(), "foo")'
> intersect(list(), "foo")
list()
