    Do not allow copying a separator without a following par end.
    
    This makes virtually impossible copying a separator inset whithout
    also copying the end of paragraph. These insets are not supposed to
    be directly inserted by users. For example, the parbreak version
    represents a LaTeX paragraph break, not a LyX one. So, if it is
    possible to copy and paste it by alone, an unsespecting user may be
    surprised to see a paragraph break in the output but not on the LyX
    screen (because of the lack of indentation, for example).
    In this way, it also becomes a LyX par break from a user point of
    view, not any more useful than simply introducing a par break by
    hitting <return> (except in those cases where it makes a difference,
    in which case they are automatically inserted by LyX).
