This was one of the first issues I raised, in June this year. I think it
was my first bug report:
http://code.google.com/p/lilypond/issues/detail?id=1134
Lilypond's _only_ failure here is missing that the both notes need
accidentals, because she compares only with previous notes, not
simultaneous
notes. (She does compare all voices.) If we force an explicit accidental
with
'!'
<< { fis'4 } \\ {f'!4} >>
then Lilypond prints both a sharp and a natural -- with the natural always
closer to the notehead so it is distinct from an extra natural that just
cancels an earlier accidental.
Marco, and Phil, is sharp-natural-notehead the desired notation for this
situation? (I prefer it to the double-stem method, which I have seen only
in
Gardner Read's textbook, the "Displaying complex chords" snippet, and
nowhere
else.)
