It does.

I got the bar number printed using a little hack:

stopThisMeasure = \applyContext
#(lambda (x)
  (ly:context-set-property!
    (ly:context-property-where-defined x 'measurePosition)
      'measurePosition
      (ly:moment-sub (ly:context-property x 'measureLength) 
(ly:make-moment 1 128) )))

then "\stopThisMeasure s128" has the desired effect. Probably because 
the measure is ended in the normal way. Still some horizontal space is 
inserted by this, but it is minimal because of the 128th rest. I can 
live with that.

Thanks a lot!
