CMake uses the [KEYWORDS introduce a LIST of arguments] convention in
lots of other places, so I think people need to get over that
confusion anyway. It's definitely better than the system this patch
introduced, which caused Bigcheese to suggest that I remove a
positional argument when I reduced it to an empty string.
