Re: Extending beamed stems

[Henrik Frisk]

Your suggested solution seems to be the way to do it. I tried it quickly, but 
the NoteColumn #'force-hshift didn't do anything. Now, that may be because I am 
not using the 2.5 yet and i didn't start looking in the manual for a way to 
achieve this in 2.4. I will upgrade and try again and in any event, you have 
pointed me in the right direction, and I am sure i will be able to find out. I 
am still curious to find out why the Voice.Beam #'X-extent and Voice.Beam 
#'extra-offset doesn't have any effect. This was what I tried at first. Anybody 
knows why me and Daniel are unsuccessful in getting the desired effect?
