Again: \rest spacing

[Thomas Scharkowski]

Hello,

maybe my last post was not clear enough, so I try again:
In polyphonic situations the vertical position of rests entered with 
\rest is not as expected.
The attached code produces correct positions for bar 1 (which is 
"monophonic" and wrong positions for bar 2, which is polyphonic.
I am quite sure this did not appear in previous versions.

Thank you
Thomas
