[Rd] SweaveInput + keep.source = TRUE trouble

[Duncan Murdoch]

  This is fixed now in R-devel and the beta version.  The fix isn't 
perfect:  if you use \SweaveInput, you lose the error reporting that 
gives line numbers from the original file.  It should be possible to 
have both, but I think the changes to implement that are too large to 
consider in a beta.
