feature request: stem length should scale for scaled/cue notes

[Kieren MacMillan]

Hello all,

I searched the issue tracker and LSR, but couldn’t find anything related to 
this.
(Apologies if I missed it.)

Please consider the output of following snippet:

%%%  BEGIN SNIPPET
\version "2.19.35"

cees = { c'8 8 8 8 }

tinyteeny = {
  \time 2/4
  \cees
  \tiny \cees
  \teeny \cees
  \new CueVoice { \cees }
  << R2 \new CueVoice { \cees } >>
}

\score {
  \new Staff \tinyteeny
}
%%%  END SNIPPET

The stem lengths are identical for all notehead sizes; note also that this is 
independent of whether CueVoice is explicitly used, and if so whether the 
CueVoice is simultaneous with another voice.

While this output is perhaps logical/intuitive, it looks odd to my eye. And 
it’s definitely not the accepted convention (cf. Gould, p. 569: “Cue notation 
is about three-quarters the size of full-sized notation […] All notation 
symbols that are part of the cue […] are scaled down. Stem lengths are 2-2½ 
stave-spaces long.”).

I think Lilypond should [optionally?] calculate the stem length *relative to 
the notehead size*, so that the smaller notes look like “real music”.
Thoughts?

Thanks,
Kieren.
