The change was done after considerable discussions and a long search
for other possible solutions: The old version inserted a hard path to
Sweave.sty into the .tex file. That did never work on most
installations on an admittedly rather exotic platform: Windows in an
English locale. TeX does not like spaces in paths, and
"c:/program files/R/..."  is where R ends up by default.
One can use the "short path", but that contains tildes which TeX
doesn't like in paths either.

Another possibility is to add the R texmf directory to your TeX input
path, unfortunately the R install dir on Windows conatins version
numbers by default. However, the good news is that Sweave.sty isn't
exactly changing on a rapid pace.
