Ok, I figured out the problem.  I had been looking for some sort of 
conflict in my init.el file that could be causing the problem -- 
forgetting that I also had an emacs-custom.el file where I had done a 
couple of ESS customizations two years ago.  Right away I noticed that I 
had this line in the file:

  '(ess-r-pager "emacsclient")

Removing that line solves the problem entirely.  Now help(), ?, and C-c 
C-v all work as expected as well as page(), edit(), and fix().

and now I have these options set automatically after I start an R session:

 > options()$pager
  [1] "cat"
  > options()$editor
  [1] "emacsclient"
  > options()$help.pager

Apparently these are as they should be.

Sorry for all the noise!
