Yeah, that got me trying the redirection, too. But the "If ssh does not
have a terminal associated" part is actually what counts, it seems.
Because ssh falls back to /dev/tty if stdin doesn't work. Guess the
stdin redirect might just be required in some cases, where it would use
/dev/stdin directly, so you force it to try /dev/tty and then use
SSH_ASKPASS.
