[Rd] readBin() can read beyond end of raw vector

[Henrik Bengtsson]

FYI, in R v2.5.0 alpha, readBin() can be used to read beyond end of raw vector:

> bfr <- as.raw(1:10)
> readBin(con=bfr, what="raw", n=20)
 [1] 01 02 03 04 05 06 07 08 09 0a

> readBin(con=bfr, what="integer", n=20)
[1]  67305985 134678021

> readBin(con=bfr, what="integer", size=4, n=20)
[1]  67305985 134678021

> readBin(con=bfr, what="integer", size=2, n=20)
 [1]    513   1027   1541   2055   2569  29537  29541      0      9  16384
[11]   9376    453 -18208    505 -18328    505      9      0      0      0

> readBin(con=bfr, what="integer", size=1, n=20)
 [1]   1   2   3   4   5   6   7   8   9  10  97 115 101 115   0   0   9   0   0
