Good question.  I find the "accidental" behaviour of shells like tcsh
ideal - the characters are echoed when you type them (because the tty
is in cooked mode) which makes delete (etc) usable, and again when the
shell reads them (because it does its own echoing), which lets you see
what commands you've executed (easily forgotten :-).
