I created a file bookmark. Now when I open it using `C-u C-x j y` I need to answer 3 questions:

    Jump to bookmark-file bookmark (test): <enter>
    SWITCH to new bookmark file, instead of just adding it? (y or n) y
    Save current bookmarks before loading? (y or n) y

How to get rid of these questions and just silently load the file answering "y" everywhere?
