Interestingly, this rule isn't a very strong one in piano music,
especially if seconds occur.  Most engravers prefer to tweak
accidentals horizontally as much as possible, dropping the octave
alignment.  All my examples were real examples found in well-engraved
editions of Liszt, Chopin, etc.

The idea is that the position of the accidentals imitate the positions
of the affected notes in the chord; this avoids that one of the three
accents is too far away.  Again, I've found many examples, and I like
it, but maybe this is my personal opinion.

BTW, I was in doubt whether the lowest accidental can really move that
far to the right for this interval (since it still touches the note
above); it is perhaps difficult to code also.
