Any SwUndoFormatCreate that is added during CopyImplImpl() must go before
SwUndoCopyDoc on the undo stack.
SwNodes::CopyNodes() is pretty much the only thing of substance there
that runs with Undo enabled; CopyBookmarks() and lcl_DeleteRedlines()
and CopyFlyInFlyImpl() have it disabled.
Let's see if the fix is really this simple...
