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

[russell-lenth at uiowa.edu]

I am so embarrassed.  I now see the syntax error in my original batch 
file; and if I correct it, it works just fine.  I don't know why I 
didn't get a DOS error with it; if I had, it obviously would have saved 
me from reporting it as an R bug.  My apologies for causing trouble -- 
it definitely is not a bug in R.

best,

Russ
