Organizing multiple Git identities
How do people handle multiple git identities with github+ssh? Since you always log in as the `git` user, you can't reuse keys. I end up with an ~/.ssh/config like:  Host github-client1
    Hostname github.com
    User git
    IdentityFile ~/.ssh/id_rsa-client1

  Host github-client2
    Hostname github.com
    User git
    IdentityFile ~/.ssh/id_rsa-client2

Then clone using `git clone git@github-client1:username/repo.git` Is there a better way?
