This is probably the same underlying bug, but it is not caused by
semicolons.
Yes, it was the same bug. I think I have it fixed now, and will commit
after some more testing.

If you use keep,soure=TRUE with expand=FALSE and interpolate a code
chunk, the name of the chunkl is sent to the TeX file once for every
line in the chunk. Specifically, the source file:
%%%%%%%%%%%
\documentclass{article}
\begin{document}
<<example>>=
x<- 1
y<- 2
x+y
@
<<keep.source=TRUE,expand=FALSE>>=
<<example>>
@
\end{document}
%%%%%%%%%%%
produces the output LaTeX file:
%%%%%%%%%%%
\documentclass{article}
\usepackage{Sweave}
\begin{document}
\begin{Schunk}
\begin{Sinput}
> x<- 1
> y<- 2
> x + y
\end{Sinput}
\begin{Soutput}
[1] 3
\end{Soutput}
\end{Schunk}
\begin{Schunk}
\begin{Sinput}
> <<example>>
> <<example>>
> <<example>>
\end{Sinput}
\begin{Soutput}
[1] 3
\end{Soutput}
\end{Schunk}
\end{document}
%%%%%%%%%%%

Thanks for the report. I'll take a look.
I'm now past one major time sink, and will have some time to catch up
on old problems; I'll add this to that list.

The following is 'semicolon.Rnw'

Code for panel A is

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.
