[Rd] Small nit in Sweave

[Terry Therneau]

Two small Sweave issues.

1. I had the following line in my code
   <<echo=FALSE, results="hide">>

resulting in the message
Error in match.arg(options$results, c("verbatim", "tex", "hide")) : 
  'arg' should be one of “verbatim”, “tex”, “hide”

  I puzzled on this a bit since my argument exactly matched the message,
until I thought of trying it without the quotes.

2. Where should I have reported this?  Sweave is not on CRAN so I
couldn't find the maintainer email there.  Perhaps I'm missing something
obvious though....
