Comment #17 on issue 2823 by [email protected]: Patch: Fixes position of mensural c clef
http://code.google.com/p/lilypond/issues/detail?id=2823
I've not check compiled this - my monitor problems mean I'm not currently running my Ubuntu box, but LGTM. FWIW the reason I rewrote the code that draws the "ornaments" was that I found the original rather obscure and I find my version easier to understand what is being drawn.
