Commands are executed with the -e argument of your shell.  You can
slash-escape spaces or quote them; either one should work.

If the server supports it, it sends a 'exit-status' request to the
channel with a uint32 encoded exit code.  If it exits with a signal,
an 'exit-signal' message is sent with format:
    string signal name
    bool core dumped
    string error message
    string language
