Description

Continuation of: https://github.com/haskell-nix/hnix/issues/507

The main thing there that people just do not know the Nix behavior in the base case, when the file is empty, aka when the expression is empty.

Would've been great, though, to have a human-readable error message for that base case.

This report is not all that important and can be closed.
