Need a method of force quitting when it hits an error

[10leej]

This script does not work with gentoo whehn I run it and ask it to configure neovim.

it reports "Unsupported OS" and the only escape method is to force close the terminal. IMHO This should call an exit

It should now exit correctly with the latest main branch.
