[Rd] R echoes integer literals incorrectly, under certain conditions (PR#13204)

Under certain conditions, R 2.8.0 incorrectly echoes integer literals without
the "L" suffix.  R 2.7.2 is ok.

To reproduce, create two files as follows:
a.R containing: source("b.R", echo=TRUE)
b.R containing: x <- 1L

Now execute: Rterm --vanilla --silent <a.R
This echoes:    x <- 1
It should echo: x <- 1L

This behaviour does not occur if you source("b.R") directly from the R command
prompt, or if you use R 2.7.2.
