I'm wondering when this changed (F10)? I'm sure it didn't act like this
in F9.

In F9, I would only be prompted to enter my passphrase if I sshed to a
box that accepted pubkey authentication and a ssh-agent did not already
have the key.
In F10 it asks earlier: when ssh-add is run.

But oh well, it does.
