problem in R.sh.in script (PR#272)

[oka@debian.or.jp]

I found problem in R-0.65.0/src/scripts/R.sh.in script.
When I run R program with `R -d gdb', R script say,

  /usr/local/bin/R[104]: shift: bad number

I fixed this problem by applying following patch to the script:

*** R.sh.in.orig    Fri Sep 10 13:01:10 1999
--- R.sh.in Fri Sep 10 13:01:23 1999

      --no-environ)
        USE_R_ENVIRON=false ;;
      --vanilla)
