[ESS] spurious (list ....)

[Lionel Henry]

Hello,

This is a known issue with ESS 18.10 and Emacs 27. Either dowgrade
Emacs or install dev ESS to fix this. A new release is much needed but
there's still a bunch of problems to solve. We're aiming for an April
release.

As a workaround you can add this to your config:

```
(setq ess-can-eval-in-background nil)
```

You won't get the parasite output as you type. Unfortunately this
disables all contextual help (eldoc, completions, ...).

Best,
Lionel
