RT 78814 perlfunc/open(): four items are not a triple
Reported by Niko Tyni
Commit b76cc8ba45957 made each group a quadruple without
updating the name. Take out the name altogether to avoid
this in the future.
Also update the reference to "list form" pipes to include
both the old last example and the new one.
