Crash when content of .ssh/rc outputs to stdout

[clach04]

I was messing around with https://github.com/dylanaraps/neofetch and as an experiment added it to .ssh/rc which lead to RasPiCheck crashing. I can attach a feedback crash log if that's useful. I ended up moving to .bashrc with an SSH_CONNECTION conditional check to avoid the problem (arguably, what I should have done initially ;-) again I was experimenting)

I'm not sure if this is a must-fix issue, alternative would be a FAQ added to http://eidottermihi.github.io/rpicheck/

Thoughts?
