accidentals

[Rune Zedeler]

Two questions:

1) If I've understood lily correctly, all that lily keeps track of is a
list of which pitches are currently affected by accidentals, and how
much.
Then there are properties for selecting whether to change this list when
entering acc. note (forgetAccidentals) and whether to reset at bar lines
(noResetKey).

What I need (very common notation) is a "mark this pitch as changed"
function resulting in altered pitches ALWAYS gets an accidental the next
time they are used. Eh hard to explain... Example:

(key c)

cis2 c | cis cis | c cis | cis

gives ( § = natural sign)

#O §O | #O O | §O #O | #O

Also option for using reminder accidental instead of accidental,
resulting in:

#O §O | #O O | (§)O #O | #O

2) How do I force a reminder natural-sharp?

cisis1 | cis?1

results in

xO | (#)O

instead of the expected

xO | (§#)O


I am willing to help implementing this, but first I ask here.
