Re: shortening a stem

[Janek Warchoł]

Hi Werner,

i'm performing some archeological research on emails that were sent
during my absence and i found this one:

David Nalesnik wrote a very versatile function that makes such things
very easy.  You can find it in a thread titled "generalizing offsets
to properties" on -devel.
I have no idea why this wasn't added to LilyPond yet - it's very
handy.  But i'm pretty sure its included in Urs' OpenLilyLib.

cheers,
Janek
