    Revert "Simplify mct--completions-completion-end"
    
    This reverts commit 790dc175c4cf869104797317c3607f7a47098e1d.
    
    It does not work when completion candidates contain spaces.  However, we
    still have a problem with the code we are reverting to, namely: if the
    next-completion is past a line that is fontified with
    completions-group-format then the highlight covers that whole line as
    well.
