nixConfig prompt is confusing

[ncfavier]

do you want to allow configuration setting 'extra-substituters' to be set to 'https://foo.cachix.org' (y/N)? yes
do you want to permanently mark this value as untrusted (y/N)? yes
warning: ignoring untrusted flake configuration setting 'extra-substituters'.
Pass '--accept-flake-config' to trust it

Answering "yes" at the first prompt was interpreted as "no" because it expected just "y". This is incredibly confusing.

To reproduce, run nix develop github:ghostty-org/ghostty.

It seems like you are using Lix and not Nix. Their issue tracker would be the appropriate place for reports.

Same problem on Nix 2.34.6, I've updated the output log.
