Conceptually, this seems like the wrong place to work around this problem. I would imagine the shell should expand globs before invoking any commands. Only doing it for the last one also seems odd - I guess that't the only case triggered by the current test suite, but surely we can construct inputs that have glob patterns elsewhere?
