I'm at home now and getting the following from Revolution R Open 3.2.2 on a Mac:

> dcf <- paste(c("aa: ", rep(letters, length.out=10000)), collapse="")
> writeLines(dcf, "test.dcf")

       aa
[1,] 8186

Here's what I see in the file:

$ wc -c test.dcf

   10005 test.dcf

Same results using Revolution R Open on Windows.  Also same results on
regular R 3.2.0 on Windows.
