automatically.

I'm afraid it simply isn't possible for ssh-agent to export them itself
due to how Unix works. When you run ssh-agent, you're starting a child
process, and a child process cannot set environment variables in its
parent, only for itself and its own children. ssh-agent would only be
able to do what you're asking if it were part of the shell.
The recommended ways to use ssh-agent are in its manual page:
There are two main ways to get an agent set up: The first is that
the agent starts a new subcommand into which some environment
variables are exported, eg ssh-agent xterm &. The second is that
the agent prints the needed shell commands (either sh(1) or
csh(1) syntax can be generated) which can be evalled in the call-
ing shell, eg eval `ssh-agent -s` for Bourne-type shells such as
sh(1) or ksh(1) and eval `ssh-agent -c` for csh(1) and deriva-
tives.
You could set up an alias to do that for you if you prefer, or use
keychain, or various other similar approaches.
