The option just has the name "su". It can be sudo too. I wouldn't worry about
this terminal_su option. This is just has to be set, so that spacefm doesn't
throw "no valid program found" error, now and then, because of default FHS path.
SpaceFM primarily uses graphical_su, which has been set to 'ktsuss'.

This is exactly the error I was talking about above. Once we apply this patch,
the error appearing stops and ktsuss will pop right up.

Thanks! I have attached revised patch with this email.
