ssh-copy-id doesn’t work with non-POSIX Shells (ie FISH)

When attempting to copy the ssh key to remote host it fails due to the fact that the remote host is using fish and it doesn’t support the && operator. There doesn’t appear to be an alternate way to manually copy the ssh key.

The issue names ssh-copy-id and fish but no file or test. Reproduce key copying against a remote fish shell, trace the relevant command entry point, and compare it with a POSIX shell; done means the key-copy flow works without relying on fish's unsupported && operator.
