[vograno at arbitrade.com]

system(..., intern=TRUE) splits long lines after 118th character and
discards the 119th character 

> a <- paste(rep("a", 124), collapse="")
> system(paste("echo", a), intern=TRUE)
system(paste("echo", a), intern=TRUE)
[1]
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" "aaaaa"

> 

The result is a vector of length 2 and it should be that of 1.
