According to the documentation for 2.12.3 "There is no support

where the same note occurs with different accidentals in the same

have a situation where this is required and would like to add it
as an
enhancement request.
I've copied this to bug-lilypond so an issue can get made on the
tracker,
but I doubt this will get worked on in the near future.
This issue has been discussed on the mailing lists several times
over the years. The first question is what layout such a feature
would use. One option is shown in http://lsr.dsi.unimi.it/LSR/Item?
id=505, but I guess there's no single established typesetting
practice for these situations.
This would be helpful for the jazz alt chord, if it were being
written out in piano notation. Jazz lead sheets aren't usually done
that way, though, and the chord is usually denoted by something like
Ab(alt) as a chord name above the staff. (I have noticed in photos
of recent jazz recording sessions, though, that jazz musicians now
often use proper sheet music instead of lead sheets. Must be the
change from jazz as learned in bars and clubs to jazz as learned in
conservatories and universities).
The alt chord can contain the root, 3rd, b7th and any or all of the
b5, #5, b9, #9 and sometimes further extensions.

So G(alt) could be (in worst case scenario) <g b des dis f aes ais>
I kind of like the way it's done in the example on the Wikipedia
page: two notes side by side preceded by the accidentals. About as
clear as it's going to get.
