We still don't know any rules for how this should be done: Since the fa 
notehead isn't symmetric, there are two ways of writing a merged fa notehead: 

  |
 _|
|\|
|
|

and

  |
 _|
|/
|
|

To me, it's not obvious which version that should be used in which case. Also, 
I know nothing about shaped noteheads, so I don't know anything about common 
practise. Do you have any references on how merged shaped fa noteheads 
"should" look?

(btw, I have a feeling that Han-Wen would appreciate sponsorship for fixing 
this)

(as a temporary workaround, you can probably \override Stem #'extra-offset to 
position the down stem correctly)
