[Rd] No exit codes from RTerm (Windows) (PR#9296)

[ripley at stats.ox.ac.uk]

Rterm (sic) does return an error status.  You have not provided a 
reproducible example, so here is one (done in tcsh)

% echo 'q()' | rterm --vanilla --slave || echo failed
% echo 'q(status=3)' | rterm --vanilla --slave || echo failed
failed
% echo 'stop("test")' | rterm --vanilla --slave || echo failed
Error: test
Execution halted
failed

Whatever the problem is in your case, it is not what you have erroneously 
reported as a bug.  (BTW, I knew this worked as the R scripts, including 
the build process, make heavy use of it.)

Not current: see the FAQ which asks you not to report on obselete versions 
of R.
