Thanks. In the future, I'll quote at least full sentences and everything
they refer to, to avoid confusion and make sure that context is maintained.

about this option, though I use results=tex quite often. I had to look
at the source to see where the newlines were going, and saw it there.
Could you please clarify? Thanks.
Single carriage returns are usually equivalent to spaces. Multiple
carriage returns separate paragraphs, but they are rare in code chunk
output in my Sweave usage. I normally put plain text in the LaTeX
part of the Sweave document.
Indeed, it only makes a difference for code that generates large
portions of LaTeX (such as tikzDevice).
I have checked my own .Rnw files, and I have used results=tex about
600 times, but never used strip.white.
I've also looked at the .Rnw files in CRAN packages, and
strip.white=true and strip.white=all are used there about 140 times,
but strip.white=false is only used 10 times. I think only one package
(SweaveListingUtils) uses strip.white=false in combination with
results=tex.
So while I agree Martin's "adaptive" option would have been a better
default than "true", I think it would be more likely to cause trouble
than to solve it.
I agree, given this data and considering that trimming the terminal
newline can be considered a feature. Perhaps comments are the only use
case where the newline is really important. But then I don't see how to
reliably detect comments, as the catcode for % can be changed, e.g., in
a verbatim environment. I'll consider printing a \relax after the
comment in tikzDevice, this should be robust and sufficient.
