I realize that the way my question was stated was misleading. It
was not meant as a rhetorical "You would never be able to pass
['git' 'foo bar' 'baz'] with that interface, and the patch sucks."
but was meant as a pure question "Do we want to pass such word
list?". "test_completion is almost always used to test completion
with inputs without any $IFS letters in it, so not being able to
test such an input via this interface is fine. If needed, we can
give another less often used interface to let you pass such an
input" is perfectly fine by me.
But I suspect that the real reason test_completion requires the
caller to express the list of inputs to run_completion as $IFS
separate list is because it needs to also get expected from the
command line:

I wonder if doing something like this would be a far simpler
solution:
test_completion ()
{
case "$1" in
'')
;;
*)
echo "$1" >expect &&
shift
;;
esac &&
run_completion "$@" &&
test_cmp expect output
}
