Lilypond Bug Report / Mudela Question

[Burkert Stefan ICP CD MP GSM RD K5]

Hello,

I use Lilypond 1.2.11, and I have found a problem with chords:
Diminished chords ("dim") should have a lowered 3rd and a lowered 5th, not
only a lowered 5th.
The chord names should be displayed as e.g. "Cdim" rather than "Cm-5".

Another question: I would like to generate chord names like "C/A", i.e. a C
chord with a base note A, where the base note is not necessarily part of the
normal C chord. Is there a way to enter this?

Thanks,

        Stefan
