    bookmarks: Fix on_delete_range
    
    When deleting a range that did not start at the beginning of a line,
    the bookmarks contained in the range were left in the buffer, in the
    middle of the line. This broke bookmark navigation. And in case the
    line didn't already have a bookmark at the beginning, it caused
    the bookmark pixbuf (star symbol) in the line marks to disappear.
