m7.7+ does provide the desired results, though I believe it's because  
lilypond uses only the last alteration of a particular note (ie. 7.9+. 
9- will end up 7/b9 and lose the sharp nine). This behavior might  
change (?), if I remember the tenor of that discussion, so we probably  
shouldn't rely on it forever..

  m.7+ seems more logical to me, but resulted in " error: syntax  
error, unexpected '.' " for me. Guess we can't alter a minor triad.
