Just to clarify ...

Yes, you can add the !" after the fact to avoid having it removed by
magic-space.  However, whether or not the !" is present, magic-space will
attempt to expand every history reference on the line if at any time you
type a space (and you're using the magic-space binding, obviously).

This has been fixed in 4.1.0-dev* so that magic-space recognizes when a
leading !" is present and does not expand history in that case.
