[R] Need to have more control on cat()

[Christofer Bogaso]

Thanks Barry, I agree it will work. But this approach destroys the
"indent" in the program body therefore entire body of program looks
messy, for example

cat("Here I
        put indent")

obviously looks better for someone who reads my code, than

cat("Here I
dont put indent")

Any better approach?
