I think that your problem is this:

$ ssh-add -d
Identity removed: /home/jcollie/.ssh/iddsa
(/home/jcollie/.ssh/iddsa.pub)
$ ssh-add -l
The agent has no identities.

So when ssh-agent doesn’t have your identity cached it still prints a
line of text which messes up the comparison. However, by checking the
exit code of ‘ssh-add -l’ I was able to get it to work:

alias ssh='if ! ssh-add -l >/dev/null 2>&1; then ssh-add; fi; ssh'
