There was an earlier discussion about the correctness of using ICANON for this.  Is ICANON really the right variable?

AFAICT the seeings are used like this:

(cat) and other programs that just take standard input: ICANON && ECHO
(bash), (vi) and other interactive programs: !ICANON && !ECHO
password prompts: ICANON && !ECHO

and we want to exclude only password prompts.
