Thanks for the reproducer!  That helps a lot.

I'm more inclined to do something like the attached patch; my feeling is 
that it was probably a mistake that we put the `-t STDIN` check in 
Readline rather than in Teletype, and I'd rather fix that than add an 
additional prompt.  What do you think?  It works with your reproducer, 
automatically falling back to Noninteractive.
