Further to my previous note, tweaking the properties
of ties in this way works correctly for both notes
in a two-note chord, but tweaking 'control-points 
does not work for the second note in a chord.  Here 
are a few examples demonstrating the problem:

\relative c' {

% The tied chord tested
<e~ a~> <e a>
<e^~ a_~> <e a>

% All the following tweaks work on both notes of the chord ...

<e -\tweak #'color #red ^~ a~> <e a>
<e~ a -\tweak #'color #blue _~> <e a>

<e -\tweak #'thickness #5 -~ a~> <e a>
<e~ a -\tweak #'thickness #5 -~> <e a>

<e -\tweak #'dash-fraction #0.5
  -\tweak #'dash-period #1 -~ a~> <e a>
<e~ a -\tweak #'dash-fraction #0.5
     -\tweak #'dash-period #1 -~> <e a>

% ... except for these, which have no effect on the
%     second note of the chord

<e -\tweak #'control-points
 #'((0.5 . -2) (1.5 . -6) (2.5 . -6) (3.5 . -2)) -~ a~> <e a>
<e~ a -\tweak #'control-points
 #'((1.5 . 0) (2.0 . 4) (2.5 . 4) (3.5 . 0)) -~> <e a>

<a -\tweak #'control-points
 #'((1.5 . 0) (2.0 . 4) (2.5 . 4) (3.5 . 0)) -~ e~> <a e>
<a~ e -\tweak #'control-points
 #'((0.5 . -2) (1.5 . -6) (2.5 . -6) (3.5 . -2)) -~> <a e>

}

This does seems to be a bug with the combination of 
control points, ties and chords.  Alternatively, I 
can document this as a known issue.
