Hi,

When using git over ssh, it seems that if a host (eg: GitHub.com) has multiple keys (eg: an rsa and an ed25519 ones), but only one of those keys is listed in the $HOME/.ssh/known_hosts, and the one that's not listed has a higher preference (e.g. ed25519 over rsa), then the git clone operation will fail.

I feel it should try to be more intelligent and try to use the rsa one.
