R devel - Feb 2011 - keep.source when semicolons separate statements on the one line; PS

I forgot to add the sessionInfo() information:
> sessionInfo()
R version 2.12.1 Patched (2011-01-22 r54081)
Platform: x86_64-pc-mingw32/x64 (64-bit)
. . .


The following is 'semicolon.Rnw'
> \SweaveOpts{engine=R, keep.source=TRUE}
> 
> <<xycig-A, eval=f, echo=f>>> library(SMIR); data(bronchit);
library(KernSmooth)
> @ %
> 
> Code for panel A is
> <<code-xycig-A, eval=f, echo=t>>> <<xycig-A>>
> @ %
Sweave("semicolon") yields the following 'semicolon.tex'
> Code for panel A is
> \begin{Schunk}
> \begin{Sinput}
>> library(SMIR); data(bronchit); library(KernSmooth)
>> library(SMIR); data(bronchit); library(KernSmooth)
>> library(SMIR); data(bronchit); library(KernSmooth)
> \end{Sinput}
> \end{Schunk}
(I have omitted three blank lines at the start)

With keep.source=FALSE, the commands are split onto 
separate lines, and there is no repetition.
