Ties and slurs, dashed and solid

[Alex Voice]

Hi Lilypond Experts,

In a piece of music I am currently engraving, the composer requests a combination of dashed slur on the harmonic but solid tie on the base note, and in the following it works perfectly in example A, but in B (where the harmonic remains on the note d) one gets an extra solid tie. I have tried various ways around this (see B' and B'') but neither are quite satisfactory – in B' the phrasing slur is no substitute for a tie, and in B'' the stems do not quite align convincingly.

\version "2.16.2"

\relative c'

{

\time 3/4

\set doubleSlurs = ##f

<<

{  \slurDashed 

d2.\harmonic^\markup "A" ^( | c2.\harmonic) }

{ g2.~ | g2. }

>>

% --------------

<<

{  \slurDashed 

d'2.\harmonic^\markup "B" ^( | d2.\harmonic) }

{ g,2.~ | g2. }

>>

% --------------

<<

{  \slurDashed 

d'2.\harmonic^\markup "B'" ^( | d2.\harmonic ) }

{ g,2._\( | g2.\) }

>>

% --------------

<<

{  \slurDashed 

d'2.\harmonic^\markup "B''" ^( | d2.\harmonic) } 

\\

{

\stemUp

g,2._~ | g2. 

}

>>

}

Am I missing something really obvious here!? Is there any way of losing the superfluous tie in B?

Many thanks for whatever advice or solutions you may suggest.
