Oh, it wouldn't make any difference to what is supported and what is
not: on MS-Windows we'd use the 3rd element of the lists, and on other
systems we'd use the 2nd element of the list.  The purpose would be only
to have a single variable, so the users are less likely to update one
without knowing it's not the one they're using.
