AHH! THAT'S IT!

I ran the command:
$ find / -xdev -type f -exec grep -l readline {} \;
 ... then checked all the files it indicated contained the word 
"readline" inside, and found a file (which I did not create), named 
".irbrc", which contains (among other things), the lines:
  # Prompt behavior
  ARGV.concat [ "--readline", "--prompt-mode", "simple" ]

When I renamed that file,  my irb sessions began to work correctly!

Thanks for the help. I doubt I would have found it without the tips in 
the right direction!
