You can see the '5' accidentals in `pitch-alist'. That's why I called
that a very dirty trick: then engine compares note alterations with the
key signature, which contains only non-existant alterations. That's why
the engine puts alteration on all notes it sees (unless a note with the
same pitch and the same octave has been seen before in the same
measure). As a side-effect, a warning is produced each time the
alterations from the key signature are treated.
