Well, note the "ARGV0=sh", so I'm specifically talking about glob_subst.
Just ${foo} "works" by the no_glob_subst definition.

} Is this use-case important enough to warrant yet another option?

this case it looks so obviously like a bug in the way glob_subst is
implemented that I'm not sure a new option is needed.
