measure

Thank you, the positioning is great !

But now I encounter a bug, which is very similar to this one :
http://lists.gnu.org/archive/html/lilypond-devel/2012-07/msg00748.html

I have the warning for the function before startMeasure count and the one  
after stopMeasureCount
In my case, I have two staves (two voices for each one, using partcombine)  
in a StaffGroup, and the bug only affects the second staff.
Moreover, when I tried to override a Rest's offset in staff, it crashed :
/LilyPond/usr/share/lilypond/current/scm/define-grobs.scm:2821:7: In  
procedure pure-chain-offset-callback in expression (if (ly:simple-closure?  
unpure) (ly:eval-simple-closure # unpure ...) ...):
