Having to use command line options for ssh-add and ssh-agent may be
inconvenient in some environments.

It occurs to me that the policy on when to use SSH_ASKPASS
could also be embedded in the variable itself, like this:

  SSH_ASKPASS="/path/to/script"        # like today
  SSH_ASKPASS="always:/path/to/script" # use it regardless of DISPLAY or tty
