This is probably the same underlying bug, but it is not caused by

Yes, it was the same bug. I think I have it fixed now, and will commit
after some more testing.
Now committed as r54232 in R-devel. I will wait a couple of days before
backporting it to R-patched, in case new problems show up.
This should also fix the long-standing problem of dropped comments at
the start and end of code chunks. Now, all comments should be echoed,
even in nested named chunks and with \SweaveInput.

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.
