Slight change to my previous message:


if [ -n "$STY" ]; then
    function fix_ssh_auth_sock() {
        screen -S $STY -X colon "msgwait 0\r"
        export SSH_AUTH_SOCK=`screen -S $STY -Q echo '$SSH_AUTH_SOCK\r'`
        screen -S $STY -X colon "msgwait 5\r"
    }
    export PROMPT_COMMAND=fix_ssh_auth_sock
fi

You need to check $STY or it'll start screen recursively!
