You use vi because you are lazy.

I used vi because I am too stupid to close it.

We are not the same.

I'll have to check tomarrow if RHEL and UBI do this.

Did some quick googling and looks like cent has that alias by default but doesn't do it when root. Which would explain why I do get inconsistent results with vi. I never thought about it in detail besides just knowing that there are some visual changes. Thanks for the info, I'll be noticing this now that I know!
