Use exec to save dropping back into local bash shell. about i2cssh HOT 7 CLOSED

Nice suggestion! The only thing is that you'll not see any errors if they happen and ssh gets terminated. I think I'll make it an option you can toggle.

Found an issue with this - the iterm2 Python API doesn't play well with SSH multiplexing. If an i2cssh SSH session with 'ControlMaster auto' initiates the control channel, then closing the i2cssh window will close all subsequent ssh sessions to the host which are using the same control channel, when using exec. The same issue occurs when using https://iterm2.com/python-api/examples/launch_and_run.html to start ssh sessions

I've raised an issue against iTerm2 (see URL in the comment), and here's a workaround:

@campbsb cool! I've added this to 0.0.20. Mind keeping track of this issue for me, so we can revert if this is fixed in iTerm2?
