New issue 1126 by PhilEHolmes: Tie positioning not as expected
http://code.google.com/p/lilypond/issues/detail?id=1126

Alexander Kobel reported:

In the example below the tie positioning is not quite what I'd expect to be  
the favourite option (on 2.13.11).  [N.B. the appearance is the same with  
2.12.3 and 2.13.21.  PH]

It's about chords with large intervals in between, where the tie can be  
fitted into the space between note heads. This looks strange when the inner  
ties exceed the range of the outer ties of the chord. For stem-up chords, a  
simple workaround is adding transparent notes to the chord, to block the  
empty space in between. For stem-down chords, I'd prefer the tie (between  
the c'') to be a mirrored version of the bottom tie (between the a'), i.e.  
attached to the center of the left note head instead of either the left or  
the right side of it; this I could not achieve with an additional note.

Would it be sensible to crop the range of interior ties to the union of the  
extents of the outer ties in general?

\relative c'' {
<g d g,>4~ <g d g,>
<g d b g>4~ <g d b g>
<g d g,>4~ <g d b g>
<g d g,>4~ <g d \tweak #'transparent ##t b g>

<a' c, a>4~ <a c, a>
<a e c a>4~ <a e c a>
<a e c a>4~ <a c, a>
<a \tweak #'transparent ##t e c a>4~ <a c, a>
}
