    sweave.lang: some fixes
    
    The R-block context is not included into another context containing an
    <end> tag, so "extend-parent" is useless.
    
    "style-inside" is also useless, because no style is applied to the whole
    context, the styles are applied to the different components (start, end,
    the R code).
