ssh-add2 and ssh-agent2 relationship

[David Kulp]

It's essential for the method to work.  ssh-agent opens a named pipe
(look in /tmp/ssh-<username>/) which allows all sub-processes to share
passwords for private keys.  Each sub-processor inherits the
environment space which includes an environment variable with the
pipe's name.  ssh-agent writes new password data to this pipe.
