After upgrading to from 2.9.1 to 2.10.1, I get unexpected results when calling
read.csv('/dev/stdin').  These problems go away when I call read.csv(pipe('cat

Shell session follows (bash):

~$ echo -e "a,b,c\n1,2,3" | Rscript <(echo "read.csv('/dev/stdin')")
Error in read.table(file = file, header = header, sep = sep, quote = quote,  : 
  no lines available in input
Calls: read.csv -> read.table
Execution halted
~$ echo -e "a,b,c\n1,2,3" | Rscript <(echo "read.csv(pipe('cat /dev/stdin'))")
  a b c
1 1 2 3

Note that this code worked fine for me in 2.9.1.
