William Carroll 4509fb5e50 Restore ssh-agent initialize in ~/.profile
For two days I tried using gpg-agent to emulate ssh-agent, but it did not work
the same way as ssh-agent. For example, gcert stopped working. Also, when I
tried adding keys to ~/.gnupg/sshcontrol using `ssh-add ~/.ssh/id_rsa`, the
command failed.

While the concept of reusing gpg-agent for ssh-agent appeals to me...
- Fewer agent processes
- pinentry support
...in practice, it fell short of my expectations. Some or all of this may be
because I tried running this on a gLinux machine.
