Yes, I believe the reason I didn't add the cmd /c is because I wanted
to expose the ability to not use cmd /c, at which point we probably
should indeed somehow arrange for it to be explicitly used in this
case. — then test case, not the code, is wrong (though the code is
still wrong for the :force-shell t case if that case fails to add cmd
/c without our asking — I didn't check).

PS: note that nothing is guaranteed to exist in /bin except /bin/sh
itself. Indeed, nothing else exists on NixOS.
