[ESS] How can one tell rlang not to mess up R session in ESS ?

[Dirk Eddelbuettel]

Casual searching at the rlang repo doesn't reveal anything so pardon me for
asking here but what is a simple way to tell rlang to NOT do fancy pants
color error backtraces?  At least under the theme I use ("nord", for Emacs)
it basically nixes readability by leaving a 'dark on dark' default.

Thanks in advance for any pointers.

Dirk
