Replying to myself and Tom; 'answer' to the problem:

This does indeed do the trick:

[ ! $SSH_AGENT_PID ] && eval `ssh-agent` >/dev/null
ssh-add

The /dev/null is for the 'echo $PID' it does. This puts me right
into the ssh-add password prompt, which is cool.


> Jeff: "I was expecting ssh-agent to run "bash --login""

It was. It exec'd ssh-agent correctly, and it exec'd bash
correctly, but bash barfs soon after with:

     0.000126 rt_sigaction(SIGTTIN, {SIG_DFL}, {SIG_IGN}, 8) = 0
     0.000141 kill(0, SIGTTIN)          = 0
     0.000118 --- SIGTTIN (Stopped (tty input)) ---

repeated over and over.  I'm wondering if it doesn't like the idea
that ssh-agent fed it input?  (The shell variables).  Anyway, it
gets stuck in this loop, never exiting.


> Jeff to Tom: "Thanks for the ideas :)"

I thank you again for the second point of view -- always helps!
