ssh-agent and FC13

[m.roth at 5-cent.us]

Folks,

   I've got a just-updated, and so current, FC13 system. ssh-agent should
start automagically when the user logs in, and end when they log out.
Before I did the update, it didn't start at all; now it starts, but
doesn't end on logout, and it doesn't set the environment variables
needed to use ssh-add. Oh, and the user's running gnome.

   I need to have it work this way, since that's what's needed for US
Gov't, non-DoD, PIV-II cards.

   Clues for the poor?
