At any rate, so we have the situation "at one point of time, it was
possible to trick some version of LilyPond into typesetting scordatura.
It may or may not be the case that somebody changed some parts of
LilyPond to make this work.  Also not likely that stuff would have held
up to transposing or Midi though, or that accidentals on isoglyphs
(notes looking the same but sounding different) would behave sensibly.
Nobody bothered documenting either code or usage or otherwise make this
into a supportable feature.  Try not to break it."

Since I don't have a sledgehammer available, I'll likely go scything
now.
