  It is good to know that. My work becomes easier now. :-)

  Actually I notice that line, it looked suspicious but then I got
distracted by the last sentence and I have focused on the layout changes.
"A posteriori" it is easy to justify most of our failures. :-)

  Where do I get it?

  I checked the spec files in 
http://cran.at.r-project.org/bin/linux/redhat/SRPMS/R.spec
http://cran.at.r-project.org/bin/linux/redhat/SRPMS/R-2.2.0-2.fc3.src.rpm

  since they have different dates, and they both show the same line with the
--htmlists parameter:

# Update package indices
%{_bindir}/R CMD perl %{_libdir}/R/share/perl/build-help.pl --htmllists
> /dev/null 2>/dev/null

[Last line was wrapped by my email composer.]
