Call me paranoid if you like. (Can you tell I used to work for a 
computer security company? :-) And to be honest my main motivation is 
irritation that cut-and-paste doesn't work, not security.

Nobody expects things to work if you output with one quoting scheme and 
input with a different one. But cutting and pasting from Emacs's 
read-eval-print-loop is expected to work.

No, I would like to change only the display. (I had suggested otherwise 
in comment #5 of this bug report, but was mistaken and took that 
suggestion back in later comments.)
