0.  The `-c' option is used, we're not running as `sh', we're not interactive, 
and we're
    not a login shell.

1.  $SSH_CLIENT or $SSH2_CLIENT is set

2.  The file descriptor attached to standard input is a socket or other network
    connection.

3.  $SHLVL is < 2, indicating we're the first bash in the process tree.
