and then expanded each in place. If an argument wound up empty after

Yeah, that definitely implies that it would retain position.
That arguably depends how one groups the terms - it could be read as
simply saying that the command is expanded separately from its
arguments. The fact that we're having this discussion suggests it could
do with some clarification, however. :-)
fwiw, even though the documentation for $run says that a shell is not
used unless explicitly spawned, I implicitly expected that it would
quote things in a shell-like fashion (and was then surprised by the lack
of documentary confirmation one way or the other when reading Chris's
original mail).
