Beaming question

[Urs Liska]

Hi,

I need to achieve a beaming as in the attached png, i.e. beams over 
rests with only one beam throughout the time.

a)
Is it really true that I have to do that manually in the way I did it in 
the attached file?

b)
If yes, is this a deficit in LilyPond or an indication that this isn't 
'correct' notation?

c)
I would need that in a parametrical way, so that it would correctly work 
if I did the second version with \shiftDurations.

Any ideas? Thank you
Urs
