[Issue?] hiding Accidental(s) on tied note(s) after a line break

[Kieren MacMillan]

Hi all (esp. Valentin):

Last month, there was a quick exchange about hiding accidental(s) on  
tied note(s) after a line break:
    <http://lists.gnu.org/archive/html/lilypond-user/2009-04/ 
msg00949.html>

I am running into the same issue right now, and I see why others have  
been frustrated by it...  =\
    1. Does anybody have an automatic way to get this to work as  
expected*? Maybe a callback function a la the broken slur example?
    2. Valentin: is there already an issue on the tracker to have  
this handled better? If not, can you please add it?

Thanks,
Kieren.

* I've searched through every score I own, and cannot find *any* that  
duplicate Lilypond's behaviour -- even my dodecaphonic scores [!!]  
omit the accidental(s) on line-broken tied notes. If you think about  
it, it makes sense: you don't want to make the player wonder whether  
the note has changed over the line break (i.e., that the tie is  
really a slur between notes of different pitches/alterations).
