Ties and Accidentals

[Robert Edge]

  Can anyone recommend a more elegant way to force the second of a pair 
of tied notes to display an accidental?  I have been using constructions 
such as this:

\score{{
  #(set-accidental-style 'forget)
  \clef bass
  <<
    {
      \override NoteHead #'transparent = ##t
      \override Stem #'transparent = ##t
      \override Beam #'transparent = ##t
      ees'4 ees'4


    } \\
    {
      \tieUp
      ees'4~ ees'4
    }

  >>

}}

for a couple of years now.  This was a quick hack someone posted on this 
 list and it works fine but is starting to cause trouble in some corner 
cases(ie. with whole notes or if I actually need two voices on a staff). 
 It's also a bit of an ugly hack.  Is there a better way to do this, 
and if not what would be the cost of sponsering a change so that forced 
and reminder accidentals work properly in this case?

thanks in advance.
