Request: demarkate output from server vs. local machine

[tecosaur]

I've just solved the issue I mentioned in #260, which turns out to have required a restart of the nix-daemon ... on the server, not my local machine. This provokes another request that I think might help anybody else who runs into issues where it's ambiguous whether an messages comes from the local or remote machine

error: cannot connect to socket at '/nix/var/nix/daemon-socket/socket': Connection refused
error: unexpected end-of-file

How about putting a prefix in front of each line of stdout that's forwarded from the remote machine to local stdout? E.g.

📠 error: cannot connect to socket at '/nix/var/nix/daemon-socket/socket': Connection refused
📠 error: unexpected end-of-file

Here I've used the fax machine emoji, thinking that kind of goes with the idea of "relocated output".
