[Rd] Trailing message on R CMD BATCH

[Brian Ripley]

Unix versions of R CMD BATCH have reported proc.time() unless the script 
ends in q().  E.g. if the input is 'search()' the output is

> invisible(options(echo = TRUE))
> search()
[1] ".GlobalEnv"        "package:stats"     "package:graphics"
[4] "package:grDevices" "package:utils"     "package:datasets"
[7] "package:methods"   "Autoloads"         "package:base"
>
> proc.time()
[1] 1.053 0.067 1.109 0.000 0.000
>

This was undocumented, and not shared by the Windows version.

Is it useful?
Do people want it retained?
