Tie bug

%{
The middle tie in the second bar is too long and sticks
out at both the left and right ends. This gets disturb-
ing when there are many ties and linebreaks as can be
seen in

\version "2.11.26"
\paper { line-width = 6 \cm }
\score {
        \new Staff {
                <a'~ c''>1
                <c'~ a'~ c''~>
                <c' a' c'' d''>
        }
}

%{
notes:
- the right chord must contain a second so that a note
  moves to the right (remove the d'' and the ties are
  correct)
- a low note in the right chord causes the stacking to
  be different (e.g. remove all notes c' from the chords
  and the ties are correct, because the lower notes are
  in different horizontal positions)
- the problem only occurs with whole notes.
