The remote command in 'ssh myserver foo bar' indeed doesn't have
access to functions or aliases, but it does go through a shell on the remote
end.  It simply uses a non-interactive shell.  That's why changes to PATH in
zshenv are honoured by ssh commands, and why functions aren't available
(zshrc isn't read).
